The total cost of producing x units is C(q) = 2q3- 6q2-18q+108 (a) At what level of production will the total cost be minimized? (b) At what level of production will the marginal cost be minimized? (c) At what level of production will the average cost be minimized? (use calcu- lator to approximate the solution.)
