For the cost function below, where c is the cost of producing q units of a product, find the marginal-cost function. What is the marginal cost at the given values of q? C(q) = 2002 - 99 +8;q=3, q=8, and q=11 c'(q) =( (Simplify your answer.) c'(3) = (Simplify your answer.) c'(8) =( (Simplify your answer.) c'(11)=[ (Simplify your answer.) 1/23/2020
