Answer
See the graph below.
Work Step by Step
We can easily graph the following function using a Graphing Calculator (Graph attached):
$f(x)=3\tan{(x-\frac{\pi}{2}})$
The $3$ at the beginning stretches the graph of regular $tan{(x)}$ over the $y$-axis by a factor of $3$.
Finally $-\frac{\pi}{2}$ moves the graph to the right-hand side by $\frac{\pi}{2}$.
And we get the following graph below:
