1. Describe the transformations of the sinusoidal function y = -3 cos[2(x + 45°)] – 3 compared to y = sin x 2. Give a real-life example of a periodic function (not sinusoid I). If you were to graph the function, what variables would be on the horizontal and vertical axes? Do 1ot use any of the examples that are on the test.
