ACT 1: MULTIPLE CHOICE: Choose the correct derivative for each of the given functions.

Question 1 2 pts f(x) = 10x8 - 4x + 2x3 - 18x - 9 Of(x) = 80x7 - 20x4 + 6x2 - 18 Of(x) = 80x - 20r4 + 6x2 - 18x -9 Of(x) = 80x8 - 20x5 + 6x3 - 18: Of(x) = 79x7 - 1924 + 5x2 - 17 Question 2 2 pts f(x) = 128 - 2x6 + 324 - Of(x) = 2x7 - 425 + 323 Of'(x) = 4x - 125 + 5x3 Of'(x) = 2x7 - 915 + $23 Of(x) = 4x - 975 + $23 Question 3 2 pts f(x) = (2x + 3)(4x - 5) Of(x) = 16x + 2 Of(x) = 8x + 2 Of(x) = 8 Of(x) = 16 Question 4 2 pts f(@) = 3x-5 1-2r Of (x) = -7 (1-2x)2 O f' (x) = - 3x Of(x) = -; Of (x) = - Art +4x-1 Question 5 3 pts f(x) = V3x -7 Of (I) = 231-7 Of (x) = 7 (3x-7) 2 Of(x) = -23x-7 Of (I) = 7 - 3 (3x-7) ? Question 6 3 pts y = (2x - 4)8A. IMPLICIT DIFFERENTIATION: For each problem, use implicit differentiation to find " in terms of x and y. (10 points) 1. 3y + 3xy + 4x = 0 2.x - 2xy + xy+ y =10 Final Final Answer: Answer: B. HIGHER ORDER DERIVATIVE: Find the indicated derivatives of each function. (10 points) 3. Find as of f(x) = 3x5 - 2x 4. Find the 2nd derivative of y = In(7 - x3) Final Final
