Question

The postion (in thousands of feat) of a car driving along a straight road at ime t in minutes is givan by the function y- s(t) that is pictured below 14 10 10 1)? Lat v t de ote ta velocity at the Car n thousands of feet per minute> at time t in minutes) which graph A F is the best apresentative of the derivativa uction ? ▼ 10 10 10 Nota: the vartical axs of these graphs may have bean scaled to to fit these functions. Cick ana graph to anlarge it.) Which at the following statements are tue? Selact all that apply A. Whant)pave, '(t must aso be positive. B. It) is zaro, then s(t) must be zera. C. When (t) is negative, the car is maving backwards. D. There are times when t/(t)s zero and ฮ(t) is not zero. E. The funcion represents the pasition of the car F. The funcion reprasents the accaleration ot the car G. Whan (t)s negative, the car is slowing down H. None of the above statemants are true.
