We have the equation

 

y  = Asin (Bx)

 

The amplitude  =   A   = 4   

 

Finding B   is a little tricky.....we want to  solve this  :

 

2pi / Period  = B

 

2pi  / [ 3pi / 2 ]  = B

 

4pi / 3pi  = B

 

(4/3)  = B

 

So...the equation becomes

 

y  = 4sin (4/3 x)

 

Here's the graph for one period   :  https://www.desmos.com/calculator/ncw51ksw5x
