During training, a hurdler wants to raise the height of the hurdles from the high school standard of 39 inches to the NCAA standard of 42 inches. His best race form last season included a clear over 39-inch hurdle that was modeled by h(t)= -0.025t(t-25), where t is time (in tenths of a second) after his lead leg left the track and h is the height (IN FEET)

a) Sketch the graph. Label the axes.

b) If he runs as well as his best race last year, will this hurdler clear the new height? Why or Why not?
