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

Answer:
[tex]y=3\sin(2x)[/tex]
Step-by-step 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 [tex]\pi[/tex]. Since there isn't any vertical or horizontal shift, the equation is simply:
[tex]y=3\sin(2x)[/tex]
Hope this helps!
