Jackson is conducting an experiment for his Physics class. He attaches a weight to the bottom of a metal spring. He then pulls the weight down so that it is a distance of six inches from its equilibrium position. Jackson then releases the weight and finds that it takes four seconds for the spring to complete one oscillation. Which of the following functions best models the position of the weight?
