Consider the following function. g (x) = x3 - 3 Find its average rate of change over the interval [-2, 2]. Ay Ax X Compare this rate with the instantaneous rates of change at the endpoints of the interval. g'(-2) = X g '(2 ) = X Need Help? Read It Watch It Submit Answer 7. [-/5 Points] DETAILS LARAPCALC10 2.3.017. MY The height s (in feet) at time t (in seconds) of a silver dollar dropped from the top of a building is given by s = -16t2 + 585. (a) Find the average velocity on the interval [4, 5]. ft/s (b) Find the instantaneous velocities when t = 4 and when t = 5. s' ( 4 ) = t/s s'(5) = it/s (c) How long will it take the dollar to hit the ground?
