Given that the graph represents the movement of the skate boarder, it can be seen from the graph that the y-intercept is at (0,8), the minimum point is at (0,12). From the graph we can conclude that since the y-intercept is 98, then the skate boarder started from the height of 8 ft. He is 12 feet from the left edge of the ramp. The correct answer is:
Option D.
