Work Step by Step
1. Rewrite the function as $y=3tan(\frac{\pi}{2}x+\pi)=3tan[\frac{\pi}{2}(x+2))]$, we have $p=\frac{\pi}{\frac{\pi}{2}}=2$.
2. Graph $y=tan(x)$ (blue), shift the curve 2 units to the left, shrink the curve horizontally by a factor of $\frac{\pi}{2}$, stretch vertically by a factor of 3 to get $y=3tan(\frac{\pi}{2}x+\pi)$ (red).
