Answer

$y = -4~sin~x$ We can see the graph below. The period is $2\pi$. The amplitude is 4.

Work Step by Step

$y = -4~sin~x$ When $x = 0$, then $y = -4~sin~0 = 0$ When $x = \frac{\pi}{2}$, then $y = -4~sin~\frac{\pi}{2} = -4$ When $x = \pi$, then $y = -4~sin~\pi = 0$ When $x = \frac{3\pi}{2}$, then $y = -4~sin~\frac{3\pi}{2} = 4$ When $x = 2\pi$, then $y = -4~sin~2\pi = 0$ We can see the graph below. The period is $2\pi$ The amplitude is 4
