Answer:

$y=3\sin x$

Explanation:

The function repeats the same shape after every
$2\pi$ units.

The function is symmetric with respect to the origin so it is a sine function.

The amplitude is 3 because the graph has range
$-3\le y\le 3$

The equation is of the form
$y=a\sin x$ where a=3 is the amplitude.

Hence the required equation is
$y=3\sin x$
