QUESTION 4 Calculate the derivative of the function. Then find the value of the derivative as specified. 8 f(x) = x+2 :f (0) Of'(x) = 8; f'(0) = 8 Of' ( x ) = - S : f '(0) = 2 (x + 2)- Of ' (x) = - 8(x + 2)2; f'(0) = - 32 Of ' ( x ) = - S (x + 2)2 ; f (0) = -2QUESTION 12 Find an equation for the tangent to the curve at the given point. h(x) = t 3 - 4t - 1. (2, -1) O y = 8t - 17 O y = 8t - 1 O y = 7t - 17 Oy = -1
