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 4πb = 2πb = ?
Substitute pertinent information into: y = Asin(b(x)) ± C
