TOTAL REVENUE CURVE: A curve that graphically represents the relation between total revenue received by a firm for selling its output and the quantity of output sold. It is used with the firm's total cost curve to determine economic profit. The marginal revenue curve, a key factor for determining the profit-maximizing level of a firm's output, is derived directly from the total revenue curve. This curve is constructed to capture the relation between total revenue and the level of output, holding other variables constant.
