This question has two parts. First, answer Part A. Then, answer Part B.
Part A
BRAKING DISTANCE From the time a driver sees the need to apply the brake to the point at which the car stops
completely is known as the total stopping distance. The total stopping distance d can be modeled by the equation
d = 0.0515r² + 1. 1r, where r is the speed in miles per hour. Graph the function. Interpret the key features of the
graph in terms of the quantities.
Select the graph that models this equation.
Part B
