In [[economics]], an 'inverse demand function', P = f<sup>−1</sup>(Q), is a function that maps the quantity of output demanded to the market price (dependent variable) for that output. Quantity demanded, Q, is a function of price; the inverse demand function treats price as a function of quantity demanded, and is also called the price function.<ref>Samuelson, W and Marks, S Managerial Economics 4th ed. page 35. Wiley 2003.</ref> Note that the inverse demand function is not the reciprocal of the demand function—the word "inverse" refers to the mathematical concept of an [[inverse function]].
