AMUSEMENT RIDES An amusement park ride consists of two 16-foot arms that each have a car on one end of the arm and a counterweight on the other end. The arms rotate in opposite directions. Each car has a minimum height of 3 feet above the ground. It takes each car 3 seconds to make a complete rotation. The function f(x) models the height of one car above the ground x seconds after the ride starts. (Assume the cars make complete rotations as soon as the ride begins.)
