The amount of a commodity that a customer picks relies upon the price of the commodity, the price of other commodities, earnings of the customer, and their tastes and proclivities. The demand function is an association between the amount of the commodity and its price when other factors remain constant.

The demand curve is a graphical depiction of the demand function. At higher cost prices, the demand is comparatively low, and at lower cost prices, the demand is comparatively high. Thus, any change in the price leads to movements along the demand curve. On the other hand, changes in any of the other factors lead to a shift in the demand curve.
