The function f(x) = 2(3)^x represents an exponential growth with a base of 3 and a vertical stretch of 2.

Have you ever wondered about the range of a function? Are you curious to explore the limits and possibilities of a mathematical equation? Look no further! In this article, we will delve into the fascinating world of functions, specifically focusing on the range of the function f(x) = 2(3)x. Brace yourself for an exhilarating journey through numbers and calculations as we unravel the secrets hidden within this equation.

Before we dive deeper into the range of the function, let us first understand what a function is. In mathematics, a function represents a relationship between two sets of numbers, known as the domain and the range. The domain consists of all the possible input values for the function, while the range comprises the corresponding output values.

Now, let's examine the function f(x) = 2(3)x. What does it mean? The expression 2(3)x might seem perplexing at first glance, but fear not! We can break it down step by step to gain a better understanding. Starting from the inside, 3 is raised to the power of x. This means that the value of 3 is multiplied by itself x times, where x represents any real number. Next, we multiply the result by 2, giving us our final output.

The range of a function refers to the set of all possible output values it can produce. To determine the range of f(x) = 2(3)x, we must consider the potential outcomes when various values of x are plugged into the equation. Transitioning now into the exploration of the range, let's analyze different scenarios to grasp the full extent of the function's capabilities.

When x takes on the value of 0, the equation simplifies to f(0) = 2(3)^0 = 2(1) = 2. Thus, the lowest possible output value is 2. As we increase the value of x, we witness the exponential growth of the function. For instance, when x = 1, f(1) = 2(3)^1 = 2(3) = 6. Here, the function has already surpassed its initial value and moved beyond.

Continuing our exploration, let's consider negative values for x. When x = -1, f(-1) = 2(3)^(-1) = 2(1/3) = 2/3. In this case, the output is a fraction between 0 and 1, showing us that the function can produce values below 1 as well.

As we move further into the negative values of x, the function continues to generate outputs less than 1. However, it is important to note that the closer we get to negative infinity, the closer the function approaches zero. In mathematical terms, the range of f(x) = 2(3)x as x approaches negative infinity is (0, 1).

On the other end of the spectrum, as x tends towards positive infinity, the function grows exponentially. The range in this case is infinite, stretching towards positive infinity. This means that f(x) can produce arbitrarily large positive values as x becomes larger and larger.

In summary, the range of the function f(x) = 2(3)x is (0, +∞), which denotes all positive real numbers starting from 0 and extending to infinity. This remarkable result showcases the incredible versatility and power of exponential functions. So, the next time you encounter the equation f(x) = 2(3)x, remember the vast range of possibilities it encompasses.

Now that we have explored the range of this function, it is time to reflect on the journey we have embarked upon. From understanding the basics of functions to unraveling the intricacies of the range, we have delved into the world of numbers and calculations. Hopefully, this exploration has ignited a spark of curiosity within you, inviting you to further explore the vast realm of mathematics.

Introduction

The function f(x) = 2(3)^x represents an exponential function. In this article, we will explore and describe the range of this particular function. The range of a function refers to the set of all possible output values, or y-values, that the function can produce. By analyzing the characteristics and behavior of the given exponential function, we can determine its range.

Definition of Exponential Function

Before discussing the range of the function f(x) = 2(3)^x, it is important to understand the nature of exponential functions. An exponential function is a mathematical expression in which the variable appears as an exponent. In the case of f(x) = 2(3)^x, the base of the exponential function is 3, and the coefficient outside the parentheses is 2. The variable x represents the input or independent variable, while f(x) represents the output or dependent variable.

Exploring the Behavior of the Exponential Function

To determine the range of f(x) = 2(3)^x, it is helpful to observe the behavior of this type of exponential function. When the base of an exponential function is greater than 1, as in this case where the base is 3, the function will exhibit exponential growth. This means that as x increases, the corresponding y-values will also increase at an accelerating rate. Conversely, as x approaches negative infinity, the function will approach zero but never reach it. This behavior provides crucial insights into the potential range of the function.

Identifying the Lower Bound of the Range

Since the function f(x) = 2(3)^x exhibits exponential growth, it implies that there is no lower bound for the range. As x approaches negative infinity, the function will approach zero but never actually reach it. Therefore, the range of the function does not include any negative values or zero.

Determining the Upper Bound of the Range

To identify the upper bound of the range, we must evaluate the behavior of the exponential function as x approaches positive infinity. As x becomes extremely large, the output values of f(x) = 2(3)^x will also become immensely large, approaching positive infinity. Thus, the function has no upper limit or bound in its range.

Concluding the Range of the Exponential Function

Based on our analysis, the range of the function f(x) = 2(3)^x can be described as all positive real numbers. In other words, the function can produce any positive value but does not include zero or any negative values. This range is a consequence of the exponential growth exhibited by the function when x increases and the behavior of the function as x approaches negative and positive infinity.

Graphical Representation of the Range

A graphical representation of the function f(x) = 2(3)^x would further illustrate its range. As we plot points on the graph, we would observe that the y-values increase rapidly as x increases, forming an upward-sloping curve that approaches but never reaches the x-axis. The graph extends infinitely upwards, indicating the absence of an upper bound in the range, while the x-axis represents the lower bound, with no negative or zero values included.

Real-Life Applications

Exponential functions find numerous applications in various fields. One example is population growth modeling, where the exponential function can represent the rate at which a population grows over time. Additionally, exponential functions are used to model the decay of radioactive substances, the spread of diseases, and the growth of investments over time. Understanding the range of exponential functions is essential for accurately interpreting and predicting real-world phenomena.

Conclusion

The function f(x) = 2(3)^x represents an exponential function with a range consisting of all positive real numbers. By examining the behavior of this type of function, we determined that there is no lower bound or upper bound in the range. The graph of the function visually confirms this understanding, showing exponential growth as x increases and approaching but never reaching the x-axis. Exponential functions have significant applications in various fields and understanding their range is crucial for practical use and interpretation.

Introduction to the function f(x) = 2(3)x

The function f(x) = 2(3)x belongs to the family of exponential functions, where the variable x is raised to a power. In this particular case, the base of the exponential function is 3, and it is multiplied by a coefficient of 2. The range of this function refers to the set of all possible y-values that the function can output for different input values of x. In this article, we will explore and analyze the range of the function f(x) = 2(3)x, considering the impact of its base and coefficient on the resulting range.

Understanding the concept of range in mathematical functions

Before diving into the analysis of the range of the function f(x) = 2(3)x, it is essential to grasp the concept of range in mathematical functions. The range represents the set of all possible output values, or y-values, that a function can produce for various input values, or x-values. It corresponds to the vertical extent of the function's graph, indicating the values that the function can reach as x varies.

Mathematically, we denote the range of a function f(x) as Range(f), and it can be represented as a set of numbers or intervals. The determination of the range involves examining the behavior of the function and identifying the limits or restrictions imposed by its properties, such as the base and coefficient in the case of exponential functions.

Analyzing the base of the exponential function f(x) = 3x

The exponential function f(x) = 3x has a base of 3, which means that the variable x is raised to the power of 3. The base determines how the function grows or decays as x changes. In this case, since the base is positive, the function will exhibit exponential growth as x increases and exponential decay as x decreases.

When the base is greater than 1, as in the case of f(x) = 3x, the function exhibits exponential growth. This means that as x increases, the output values of the function grow at an increasing rate. The larger the value of x, the more significant the growth becomes. Conversely, as x decreases, the output values decrease exponentially.

Examining the coefficient of the function f(x) = 2(3)x

In the function f(x) = 2(3)x, there is an additional coefficient of 2 multiplying the exponential term. The coefficient affects the vertical stretching or compression of the function's graph. It modifies the amplitude or magnitude of the function's output values without changing its general shape or behavior.

When the coefficient is greater than 1, such as in f(x) = 2(3)x, the function's graph is vertically stretched. This stretching causes the output values to increase by a factor of 2 compared to the base exponential function f(x) = 3x. Consequently, the range of f(x) = 2(3)x will be greater than the range of f(x) = 3x, as the output values are amplified.

How the combination of the base and coefficient affects the range

The combination of the base and coefficient in the function f(x) = 2(3)x has a significant impact on its range. As discussed earlier, the base of 3 indicates exponential growth, while the coefficient of 2 leads to vertical stretching of the graph. This combination results in an expanded range of the function compared to f(x) = 3x.

The exponential growth of the base 3 ensures that the function's output values increase rapidly as x becomes larger. This, combined with the vertical stretching caused by the coefficient 2, amplifies the growth even further. As a result, the range of f(x) = 2(3)x will be significantly larger than that of f(x) = 3x.

Investigating the behavior of exponential functions with positive bases

To gain a deeper understanding of the range of f(x) = 2(3)x, it is valuable to investigate the general behavior of exponential functions with positive bases. Exponential functions with positive bases exhibit unique characteristics that influence their range.

When the base is positive and greater than 1, the function experiences exponential growth. This means that as x increases, the output values grow at an increasing rate. The larger the value of x, the more significant the growth becomes. In contrast, as x decreases, the output values decrease exponentially.

It is important to note that exponential functions with positive bases never reach zero or become negative. The output values may approach zero as x approaches negative infinity, but they will never actually reach zero. Therefore, the range of exponential functions with positive bases is always greater than zero.

Determining the domain and range of the given function f(x) = 2(3)x

In order to determine the domain and range of the function f(x) = 2(3)x, we need to consider the restrictions imposed by the properties of exponential functions. The domain represents the set of all possible input values, or x-values, for which the function is defined. Since there are no restrictions on the variable x in this case, the domain of f(x) = 2(3)x is the set of all real numbers.

On the other hand, the range represents the set of all possible output values, or y-values, that the function can produce. As discussed earlier, exponential functions with positive bases never reach zero or become negative. Therefore, the range of f(x) = 2(3)x will also be greater than zero.

Graphical representation of the function and its range

To visualize the range of the function f(x) = 2(3)x, let's examine its graphical representation. By plotting the function on a graph, we can observe the behavior of its output values as x varies.

The graph of f(x) = 2(3)x will exhibit exponential growth due to its base of 3. The coefficient of 2 will cause the graph to be vertically stretched compared to the base exponential function f(x) = 3x. As a result, the graph of f(x) = 2(3)x will have a steeper slope and higher y-values for the same x-values.

As x increases, the graph of f(x) = 2(3)x will rise rapidly, indicating the exponential growth. The vertical stretching caused by the coefficient 2 will amplify this growth, making the graph steeper. Conversely, as x decreases, the graph will decrease exponentially but will remain above the x-axis due to the positive base.

Examining the graph of f(x) = 2(3)x, we can observe that the range consists of all positive y-values. The graph never reaches zero or becomes negative, confirming the infinite nature of the range for exponential functions with positive bases.

Exploring the infinite nature of exponential functions' range

The range of exponential functions with positive bases is infinite, meaning it extends indefinitely in the positive y-direction. Regardless of how large the x-values become, the output values will continue to increase without bound.

This infinite nature of the range is a consequence of exponential growth. As x increases, the output values grow at an increasing rate, resulting in an unbounded range. It is important to note that even though the range is infinite, it does not include negative numbers or zero for exponential functions with positive bases.

For the function f(x) = 2(3)x, the infinite range implies that the output values can become arbitrarily large as x increases. However, they will always remain positive due to the positive base of the exponential function.

Comparing the range of f(x) = 2(3)x with other exponential functions

To gain further insights into the range of f(x) = 2(3)x, let's compare it with other exponential functions and examine the impact of different bases and coefficients on their ranges.

Consider an exponential function g(x) = a(b)x, where a and b are positive constants. If the base b is greater than 1, as in f(x) = 2(3)x, the function will exhibit exponential growth. The coefficient a will determine the vertical stretching or compression of the graph.

If we compare f(x) = 2(3)x with another exponential function h(x) = 3x, we can observe that both functions have the same base but different coefficients. The coefficient of 2 in f(x) = 2(3)x causes vertical stretching, amplifying the growth compared to h(x) = 3x. As a result, the range of f(x) = 2(3)x will be larger than the range of h(x) = 3x.

Furthermore, if we compare f(x) = 2(3)x with a function j(x) = 2x, we can observe that both functions have the same coefficient but different bases. The base of 3 in f(x) = 2(3)x leads to exponential growth, which is more rapid compared to the base of 2 in j(x) = 2x. Therefore, the range of f(x) = 2(3)x will be larger than the range of j(x) = 2x.

In conclusion, the combination of the base and coefficient in an exponential function significantly affects its range. A positive base determines the behavior of exponential growth, while the coefficient modifies the amplitude or magnitude of the output values. The function f(x) = 2(3)x, with its base of 3 and coefficient of 2, exhibits exponential growth and vertical stretching, resulting in a larger range compared to other exponential functions with different bases or coefficients.

Thank you for taking the time to read our in-depth analysis of the range of the function f(x) = 2(3)x. Throughout this article, we have delved into various aspects of this function, providing you with a clear understanding of its properties and limitations.

First and foremost, it is important to note that the function f(x) = 2(3)x represents an exponential growth model. As x increases, the output of the function grows at an exponential rate, making it an essential tool in many mathematical and scientific applications.

One of the primary factors that determine the range of this function is the base value, which in this case is 3. The base value determines the rate at which the function grows. With a base greater than 1, as in this case, the function increases indefinitely as x approaches infinity.

Furthermore, the coefficient 2 in front of the base represents a vertical transformation of the function. It scales the entire function by a factor of 2, altering its range without affecting the general shape of the graph. This means that the range of the function f(x) = 2(3)x will be twice the range of the function f(x) = 3x.

When analyzing the range of the function, it is crucial to consider whether the function is increasing or decreasing. In the case of f(x) = 2(3)x, the function is strictly increasing. This means that as x increases, the corresponding y-values also increase. Consequently, the range of the function extends infinitely upwards.

However, it is essential to note that the range of the function is not limited to positive values. Since the base value is positive, the function will always yield positive outputs. However, it does not exclude negative values. The function can produce negative values when x is a negative integer. Therefore, the range of f(x) = 2(3)x includes both positive and negative real numbers.

Another crucial aspect to consider is the domain of the function. The domain of f(x) = 2(3)x is all real numbers. This means that the function is defined for any value of x, which further supports the idea that its range extends infinitely in both positive and negative directions.

It is also worth mentioning that the function f(x) = 2(3)x never equals zero. Since the base value, 3, is positive, the function will never cross the x-axis. Therefore, the range of the function does not include zero.

To summarize, the range of the function f(x) = 2(3)x is an infinite set of positive and negative real numbers. As x approaches infinity, the output of the function increases exponentially, making it an invaluable tool in various mathematical and scientific fields.
