Work Stretching a Spring

CLMECH-N9ENBJ

The free end of a spring with spring constant $k = 75\text{ N/m}$ is located at a position of $x = 0.0\text{ cm}$ when the spring is relaxed. Assume increasing the position of the free end of the spring stretches the spring while moving the free end in a negative direction compresses the spring.
