Multiple Choice

An object weighing $W$ pounds is suspended from the ceiling by a steel spring (see figure) . The weight is pulled downward (positive direction) from its equilibrium position and released. The resulting motion of the weight is described by the function $y = \frac { 1 } { 2 } e ^ { \frac { - t } { 4 } } \cos t , t > 0$ where $y$ is the distance (in feet) and $t$ is the time (in seconds) . Use a graphing utility to select the graph of the function.
