Chapter 9 - Section 9.3 - Exponential Functions - Exercise Set: 63



Work Step by Step

We are given the function $h(x)=(\frac{x}{2})^{2}$. In general, exponential functions are written in the form $f(x)=b^{x}$ (where $b\gt0$, $b\ne1$, and $x$ is a real number). In other words, exponential functions consist of a constant that is raised to the power of a variable. Therefore, the given function is not an exponential function, because it consists of a variable term $\frac{x}{2}$ raised to the power of a constant.
