Safety research. Under ideal conditions, if a person driving a vehicle slams on the brakes and skids to a stop, the speed of the vehicle v(x) (in miles per hour) is given approximately by , where x is the length of skid marks (in feet) and C is a constant that depends on the road conditions and the weight of the vehicle. For a particular vehicle, and 4 ≤ x ≤ 144.

(A) Describe how the graph of function v can be obtained from the graph of one of the basic functions in Figure, page 19.

(B) Sketch a graph of function v using part (A) as an aid.
