Suppose that the manager of a firm operating in a perfectly competitive market has estimated the average variable cost function to be:AVC = 4.0 – 0.0024Q + 0.000006Q2Fixed costs are $500.The marginal cost function is:a. MC = 4.0 – 0.0048Q + 0.000018Q2 b. MC = 4.0 – 0.0012Q + 0.000002Q2 c. MC = 4.0Q – 0.0024Q2 + 0.000012Q3 d. MC = 4.0 – 0.0048Q + 0.000012Q2 e. None of the above
