1. To obtain the graph of y = asinb (x - h) + k ,
explain what each of the values of a, b, h, and k affects the graph of function y = sin x
a affects the amplitude and flips the graph around the x-axis if negative
h shifts the graph L if it is a neg value and R if it is a pos value (there is a neg sign in front of h in your example)
k shifts the graph up if positive....down if negative
