2. Calculating marginal revenue from a linear demand curve The blue curve on the following graph represents the demand curve facing a firm that can set its own prices. Use the graph input tool to help you answer the following questions, You will not be graded on any changes you make to this graph. Note: Once you enter a value in a white field, the graph and any corresponding amounts in each grey field will change accordingly. Graph Input Tool Market for Goods On the graph input tool, change the number found in the Quantity Demanded field to determine tha prices that correspond to the production of 0 , 2 , 4,5,6,8, and 10 units of outbut. Calculate the total revenue for each of these production levels. Then, on the fallowing graph, use the green points (triangle symbol) to plot the results. Calculate the total revenue if the firm mroduces 2 versus 1 units. Then, calculate the marginat revence of the second unit produced. The marginal revenue of the second unit produced is Calculate the total revenue if the firm produces 4 versus 3 unts. Thop, calculate the marginal revenue of the fourth unit produced. The marginal revenue of the fourth unit produced is Based on your answers from the previous question, and assuming that the marginal rovenue curve is a straight hine, use the black fine (plus symbol) to plot the firm's marginal revenue curve on the following graph. Comparing your total revenue oraph to you marginal revenue graph, you can see that total revenue is at the output at which marginal revenue is equal to zero
