Question

3. A scientist recorded the movement of a pendulum for a period of time. The scientist began recording when

the pendulum was at its resting position. The pendulum then moved right (positive displacement) and left
(negative displacement) several times. The pendulum took 5 s to swing to the right and then return to its
resting position. The pendulum's furthest distance to either side was 7 in. Graph the function that represents
the pendulum's displacement as a function of time.
(a) Graph the function (include at leaſt one full cycle).
(b) Write an equation to represent the displacement of the pendulum as a function of time.
