Introduction

When dealing with functions, it's essential to understand the concept of the domain. The domain of a function is the set of all possible input values (x-values) for which the function is defined. In other words, it's the set of all possible x-values that the function can accept without resulting in an undefined or imaginary output. In this article, we'll explore the domain of the function $f(x) = 2(3)^x$.

Understanding Exponential Functions

Before we dive into the domain of the function $f(x) = 2(3)^x$, let's take a closer look at exponential functions. An exponential function is a function that can be written in the form $f(x) = a^x$, where $a$ is a positive real number. The base $a$ determines the rate at which the function grows or decays. In the case of the function $f(x) = 2(3)^x$, the base is $3$, which means that the function will grow exponentially as $x$ increases.

The Domain of Exponential Functions

The domain of an exponential function $f(x) = a^x$ is all real numbers. This means that the function is defined for any real value of $x$. However, it's worth noting that the function may not be defined for complex values of $x$. In the case of the function $f(x) = 2(3)^x$, the domain is also all real numbers, since the base $3$ is a positive real number.

The Function $f(x) = 2(3)^x$

Now that we've discussed the domain of exponential functions, let's take a closer look at the function $f(x) = 2(3)^x$. This function is an exponential function with a base of $3$ and a coefficient of $2$. The function can be rewritten as $f(x) = 2 \cdot 3^x$, which makes it clear that the function is an exponential function with a base of $3$.

Finding the Domain of the Function

To find the domain of the function $f(x) = 2(3)^x$, we need to consider the values of $x$ for which the function is defined. Since the function is an exponential function, it is defined for all real values of $x$. However, we need to consider the possibility of the function resulting in an undefined or imaginary output.

Analyzing the Function

Let's analyze the function $f(x) = 2(3)^x$ to see if it results in any undefined or imaginary outputs. We can start by considering the case where $x$ is a negative integer. In this case, the function can be rewritten as $f(x) = 2 \cdot 3^{-x}$. Since $3$ is a positive real number, $3^{-x}$ is also a positive real number. Therefore, the function is defined for all negative integers.

Considering Complex Values of $x$

Now let's consider the case where $x$ is a complex number. In this case, the function can be rewritten as $f(x) = 2 \cdot 3^x$. Since $3$ is a positive real number, $3^x$ is also a positive real number. Therefore, the function is defined for all complex values of $x$.

Conclusion

In conclusion, the domain of the function $f(x) = 2(3)^x$ is all real numbers. This means that the function is defined for any real value of $x$. We've also considered the possibility of the function resulting in an undefined or imaginary output, and found that it does not result in any such outputs.

Final Thoughts

The domain of a function is an essential concept in mathematics, and it's crucial to understand it when working with functions. In this article, we've explored the domain of the function $f(x) = 2(3)^x$, and found that it is all real numbers. We've also considered the possibility of the function resulting in an undefined or imaginary output, and found that it does not result in any such outputs.
