The function graphed is of the form y=a sin bx or y=a cox bx, where b>0. Determine the equation of the graph.

The equation is of the form y=asinbx
The amplitude of the graph is a=3 unit
The period is
[tex]\frac{\pi}{2}[/tex]Thus,
[tex]\frac{2\pi}{b}=\frac{\pi}{2}\Rightarrow b=4[/tex]Thus the equation becomes,
y=3sin(4x)
