## Homework Statement

I have to fill in the missing info...

Y=A*Sin[B(x-c)] +D

A = 3. For finding the amplitude all I have to do it multiply 1/2 by the range?

D = 3. For finding upward shift all I have to do is see if the center has moved up?

period = 4pi/3 so B = 3/2

I am confused on how to find the phase shift... can I implement a,b, and d into my equation and solve for C somehow?

By just looking at the picture is looks like c could eaither be + or - pi/3 ?

But I would like to solve for this algebraically.
