I really need help with this question . Can someone please help me with this? 

1.the graph of a sinusoidal function passes through (0,1), has a maximum point at (pi/2 , 3), and subSequent maximum point at (7pi/6 , 3).

A.determine the amplitude ,period ,midline and range of the function [hint: determine the period, and show the point (0,1) is 3/4 of the period to the left of the point (pi/2 , 3). Why does this guarantee (0,1) is on the midline?]
