When we look at the marginal revenue curve versus the demand curve graphically, we notice that both curves have the same intercept on the P axis, because they have the same constant, and the marginal revenue curve is twice as steep as the demand curve, because the coefficient on Q is twice as large in the marginal revenue curve. Direct link to James Shea's post Profit margin is always g, Posted 8 years ago. So, Marginal profit is the derivative of the profit function, so take the derivative of P ( x) and evaluate it at x = 100.

While marginal revenue can remain constant over a certain level of . [3] This is useful because economists typically place price (P) on the vertical axis and quantity (Q) on the horizontal axis in supply-and-demand diagrams, so it is the inverse demand function that depicts the graphed demand curve in the way the reader expects to see. By decreasing its price, the company will receive less marginal revenue for each additional unit sold.
