$y = 3~sin~\pi x$ We can see the graph below. The period is $2$ The amplitude is 3
$y = 3~sin~\pi x$ When $x = 0$, then $y = 3~sin~0 = 0$ When $x = \frac{1}{2}$, then $y = 3~sin~\frac{\pi}{2} = 3$ When $x = 1$, then $y = 3~sin~\pi = 0$ When $x = \frac{3}{2}$, then $y = 3~sin~\frac{3\pi}{2} = -3$ When $x = 2$, then $y = 3~sin~2\pi = 0$ We can see the graph below. The period is $2$ The amplitude is 3
