9-101.

The graph below is the result of a transformation of

*y*= sin*x*. Find a possible equation for the function. Homework Help ✎

The vertical shift is down 4. There is no horizontal shift.

So a whole cycle (period) is 4π. Calculate the frequency *b*: *bp* = 2π, so 4π*b* = 2π*b* = ?

Substitute pertinent information into: *y* = *A*sin(*b*(*x*)) ± *C*
