Just check this equation for me based on the info in the question below. Here is the equation I made: 2 sin (2x) - 2

Could you also help me with the graph?

We have the form

y = Asin (Bx) + C

A= the amplitude = 2

B = 2pi/period = 2pi / pi = 2

C = the normal midline is y = 0

y = - 2 shifts this down 2 units....so C = -2

The function is

y = 2sin (2x) - 2 YOU WERE CORRECT!!!
