a. Find the first, second, and third derivatives of the following total cost function:
TC(Q) = Q^3 - 8Q^2 + 500Q + 180
b. Find the average cost, AC = TC/Q, and its minimum: [Hint: Use this link to find the minimum value]
c. Find the average variable cost, AVC = TVC/Q, and its minimum:
d. Show that the marginal cost, MC, curve passes through the minimum of the AC and the AVC curves:
