# How do you plot AFC, AVC and MC cost curves for the total cost function TC = 100 + 40Q - 15Q^2 + 5Q^3?

TC = 100 + 40Q - 15Q(squared) + 5Q (to the third power), calculate the

a. average fixed cost function (AFC)

b. average variable cost function (AVC)

c. marginal cost function (MC)

Draw a diagram with all three curves plotted on it.
