c(y)=y38y2+30y+5. The firm's marginal cost function is MC(y)=3y216y+30. 3.1 What is the firm's average variable cost function? 3.2 At which level of output is the marginal cost equal to average variable cost? 3.3 For which values of output is the average variable cost falling? For which values of output is average variable cost increasing? 3.4 Draw a graph with output on the x-axis and costs on the y-axis. Illustrate the average variable cost and marginal cost. Make sure that your answers above are matching your graph. Label the intercept for marginal cost and average marginal cost. c(y)=y38y2+30y+5.
