Question

write an equation of the sine function with amplitude 4, period 4 pi, phase shift 0, and vertical shift -2

Answer 1

Okay, so first you want y=sin(x). That's the basic sine function, right?
So do you know where the amplitude goes?

Answer 2

Okay, well the amplitude goes BEFORE the sine part.


So with the amplitude, our equation is y=4 sin(x).

Do you know where to put the period?
