     Your firm has increasing marginal costs, as shown in the graph below.  Adjust the graph to show the profit-maximizing quantity. be sure you are satisfied with your positioning of the graph when you leave this page:  Profit is not maximized to the right of the profit-maximizing quantity found above because  profit is not maximized to the left of the profit-maximizing quantity found because at lower quantities
