Definitions:

Supply Curve

A graph representing the relationship between the price of a good or service and the quantity of it that producers are willing to supply.

Equilibrium Price

The market price at which the quantity of a good demanded equals the quantity supplied, leading to market stability.

Inverse Demand Function

A mathematical representation showing the relationship between the quantity demanded of a good and its price, typically derived by solving the demand function for price.

Inverse Supply

The inverse supply function represents the relationship between the price of a good and the quantity supplied, expressed as price as a function of quantity, contrasting with the typical supply function which is quantity as a function of price.
