(1 point) The position (in thousands of feet) of a car driving along a straight road at time t in minutes is given by the function y = s(t) that is pictured below. Let v(t) 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'(t)? ? v D E F (Note: the vertical axes of these graphs may have been scaled to to fit these functions. Click on a graph to enlarge it.) Which of the following statements are true? Select all that apply. [3 A. When DC) is positive, 0' (t) must also be positive. [3 B. There are times when v'(t) is zero and v(t) is not zero. C] C. The function 11" represents the acceleration of the car. [:1 D. When v'(t) is negative, the car is moving backwards. C] E. The function v' represents the position of the car. [:1 F. If v'(t) is zero, then v(t) must be zero. [3 G. When v'(t) is negative, the car is slowing down. [3 H. None of the above statements are true. . 2+h38 (1 point) The limit 1m?) % represents f' (a) for some function f and some number a. Find f (x) and (I. ha fa): a
