The position {in thousands of feet} ofa car driving along a straight road at time t in minutes is given by the function y = alt] that is pictured below. 14 Let vlt] denote the velocity of the car [in thousands of feet per minute) at time t {in minutes}. Which graph AF is the best representative of the derivative function v'ft]? ? v 12 6 10 10 A C 2 6 2 10 D m F(Note: the vertical axes ofthese graphs may have been scaled to to fit these functions. Click on a graph to enlarge it.) Which ofthe following statements are true? Select all that apply. Cl A. When 1r'{a'.} is negative. the car is slowing clown. Cl B. When 11\"} is positiver p'l} must also be positive. Cl C. The function 1f represents the acceleration ofthe car. Cl D. The function 11' represents the position of the car. D E. There are times when u'{t} is zero and 11\"} is not zero. '3 F. If v'ft} is zero. then vt} must be zero. '3 G. When v'{t} is negative. the car is moving backwards. l:' H. None of the above statements are true
