Question

This is urgent! I am willing to give lots of points for this! Please help! thanks.

Answer 1

`y=3\sin(2x)`

Explanation:

To find the equation of a sinusoidal curve, you need to know the period and the amplitude. The amplitude can clearly be seen to be at 3, while the period is just
`\pi`. Since there isn't any vertical or horizontal shift, the equation is simply:

`y=3\sin(2x)`

Hope this helps!
