Answer
The graph of $y=\tan{x}$, $\frac{\pi}{2} \le x \le \frac{\pi}{2}$ is a reflection about the line $y=x$ of the graph of $y=\tan^{-1}{x}$.
Refer to the graph below.
Work Step by Step
Use a graphing calculator to graph the given functions to obtain the graph below.
Notice that the graph of $y=\tan{x}$, $-\frac{\pi}{2} \le x \le \frac{\pi}{2}$ is a reflection about the line $y=x$ of the graph of the function $y=\tan^{-1}{x}$.
