Consider the graph of y = k + b sin (x-h)/h .
a. What effect does k have on the graph of y = k + sin x?
b. What effect does b have on the graph of y = b sin x? What is the effect if b is negative?
c. What effect does a have on the graph of y = sin(y/a)?
d. What effect does h have on the graph of y = sin (x - h)?
