Suppose a ﬁrm’s cost function is C = 2 Q 2 . What is its marginal costs, MC ? What is its average cost, AC ? 4. Suppose a ﬁrm’s cost function is C = 10 Q . What is its marginal costs, MC ? What is its average cost, AC ? 3 Monopoly Consider the following market demand: P = 24-Q . The cost of producing the good is given by C = Q 2 .
