Question

Es - Determine the equation for the function shown on the graph.

Answer 1

Answer:

$y=3\sin x$

Step-by-step 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 $y=3\sin x$
