Solve the problem. 3) Compute the instantaneous rate of change of the function at at x = a. f(x) = x2 + 3x, a = 5. A) 13 B) - 10 C) 15 D) 10 3) 4) 4) The profit in dollars from the sale of x thousand compact disc players is P(x) = x3 - 5x2 + 3x + 8. Find the marginal profit when the value of x is 6. A) $90 B) $98 C) $59 D) $51 5) 5) Let C(x) be the cost function and R(x) the revenue function. Compute the marginal cost, marginal revenue, and the marginal profit functions. C(x) = 0.0003x3 -0.036x2 + 300x + 10,000 R(x) = 350x A) C'(x) = 0.0009x2 + 0.072x + 300 R'(x) = 350 P'(x) = 0.0009x2 + 0.072x + 50 B) C'(x) = 0.0009x2 - 0.072x + 300 R'(x) = 350 P"(x) = 0,0009x2 - 0.072x - 50 C) C'(x) = 0.0009x2 - 0.072x + 300 R'(x) = 350 P'(x) = -0.000972 +0.072x + 50
