The distance a car travels before coming to a stop once a driver hits the brakes
is related to the speed of the car when the brakes were applied. The graph of f 
(shown below) is a model of the stopping distance (in feet) of a car traveling
at diffe

One data point on the graph of f appears to be (80, 1000). What do you think this point represents in the context of this problem? Explain your reasoning.

Estimate the stopping distance of the car if the driver is traveling at 65 mph when she hits the brakes. Explain how you got your answer

Estimate the average rate of change of f between x = 50 and x = 60. What is the meaning of the rate of change in the context of this problem?

What information would help you make a better prediction about stopping distance and average rate of change for this situation?
