# Cost Functions

Given the total cost function:

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)

Please show calulations and Draw a diagram with all three curves plotted on it.
