KEY CONCEPTS The transformation of a sine or cosine function f(x) g(x) = af[k(x - d)] + c. a > 1 is a vertical stretch 0> la| > 1 is a vertical compression a 1 is a horizontal compression 00 is a phase shift to the right |d units d0 is a vertical translation up | c| units c50 is a vertical translation down | c) units The period of the transformed function is given by A 2. De 1. Determine the amplitude and period of each sinusoidal function. Then, gra transform the graph of y = sin x to a) sketch a graph of each function. a) y = 4 sin 9x b) y = -2 cos 5x c) y - 7 sin x d) y = 3 cos 6.x e) y - -3 sin x b) Dy = 3 cos ex
