Inverse Demand Function: Price as a Function of Quantity

A fundamental principle of market behavior states that the price consumers are willing to pay for a good decreases as the quantity available in the market increases. Given this principle, which of the following mathematical expressions, where P is price and Q is quantity (and Q > 0), could NOT represent a valid relationship between price and the quantity demanded?

Validating a Demand Function

Consider an inverse demand function given by P = 100 / (Q + 5), where P is the price and Q is the quantity demanded (Q > 0). This function is consistent with the economic principle that the price consumers are willing to pay for a good decreases as the quantity available increases.

Evaluating a Pricing Strategy

Match each mathematical function, which expresses price (P) in terms of quantity (Q > 0), to the description that best characterizes its adherence to the economic principle that the price consumers are willing to pay for a good decreases as the quantity available increases.

Constructing a Valid Demand Function

For an inverse demand function, expressed as P = f(Q), to be consistent with the general economic principle that an increase in quantity leads to a decrease in the price consumers are willing to pay, the derivative of the function, f'(Q), must be __________.

An economist is presented with a mathematical model for the price (P) consumers are willing to pay for a certain quantity (Q) of a product, expressed as P = f(Q). To determine if this model is consistent with the principle that price falls as quantity rises, they must follow a specific analytical procedure. Arrange the following steps into the correct logical order.
