Firm’s total cost function is of the form of TC=2Q + 14 (i.e., a firm’s fixed costs are 14 and the variable costs are 2 per unit). The corresponding profit function is of the form 𝜋 = AQ2 + 𝛽Q + F . The firm makes a loss of 6 when Q=1 and a profit of 4 when Q=6. a)

(10 p.) Find A, 𝛽 and F.

b) (10 p.) Find the break-even points and hence find the maximum profit.

c) (10 p.) Find an expression for total revenue and deduce the demand function.
