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 $y = \frac { 1 } { 2 } e ^ { - \frac { t } { 4 } } \cos 2 t , t 0$ 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.
