Question

The graph in the accompanying figure (Figure 1) shows the magnitude of the force exerted by a given spring as a function of the distance x the spring is stretched.

Figure1 of 1
A graph of force F as a function of distance x. The force is measured from 0 to 350 newtons on the vertical axis. The distance is measured from 0 to 8 centimeters on the horizontal axis. A graph curve starts from the origin and rises linearly to approximately 7 centimeters and 350 newtons.
