In Canada's Wonderland there is a roller coaster that is a continuous series of identical hills that are 19 feet high from the ground. The platform to get on the ride is on top of the first hill. It takes 4 seconds for the coaster to reach the bottom of the hill 7 feet off the ground. 1) Assuming that the roller coaster follows a sinusoidal pattern, sketch a graph of the roller coaster's height on the coordinate grid below. (Use the Draw Menu!) 20 -19 -18 -17 -16 -15 -14 -13 -12 -11 -10 -9 8 -7 6 5 4 3 2 2) What is the amplitude of the function? 9 10 11 3) What is the midline/vertical shift of the function? 12 13 14
