A set of points in the plane is the graph of a function if and only if no vertical line intersects the graph in more than one point. Example 3. The graph of the equation y 2 = x + 5 is shown below. By the vertical line test, this graph is not the graph of a function, because there are many vertical lines that hit it more than once.
Revenue function = (price per unit) . (quantity of units) Symbols: R = p.x Cost function = (average cost per unit) . (quantity of units) Symbols: C = C.x Profit function = revenue − cost Symbols: P = R−C Sometimes in a problem some of these functions are given. Note: Do not confuse p and P. The price per unit p is also called the demand function p. Marginal Functions:
