Find g'(x) for the given function. g(x)=7x g'(x) = 7 21/72 An object dropped from rest from the top of a tall building on Planet X falls a distance d(t) = 7t feet in the first t seconds. Find the average rate of change of distance with respect to time as t changes from t = 4 to t = 8. This rate is known as the average velocity, or speed. feet The average velocity as t changes from 4 to 8 seconds is sec (Simplify your answer.) By determining f'(x) = lim f(x + h) - f(x) h find f'(8) for the given function. h0 f(x)=3x f'(8)= 127 - - 2 x (Simplify your answer.)
