Now lets look at more than 1 change at a time, when both the amplitude and the midline are not 1. Consider f(x)=2 cos(0) - 3: YA + HP -2 - - 2 -3 -4 -5 -6 + k 3373 32 Here are some questions for discussion: "What is the midline of f? Explain how you know." . "What is the amplitude of f? Explain how you know."
