The plot below shows the marginal cost (in red) and marginal revenue (in blue) from selling q units of a certain product are plotted below, as functions of q. 300 2000 I MR 100 MC 0 10 20 30 For each event below, indicate the q-value(s) where it occurs, or state that there are none. Provide brief justification in terms of the behavior of MR and MC observable from the graphs above. (4 points each) a) The cost function has a local minimum i b) The cost function has an inflection point c) The revenue function has a local minimum d) The revenue function has a local maximum e) The profit function has a local minimum. f) The profit function has a local maximum (You may assume any relevant point(s) on the graphs have been marked with a dot.)
