What is a demand curve equation?


Answer by  rajatanand (43)

Mathematically the demand curve equation shows a negative relation between price (P) and quantity (Q) and is expressed as Quantity (Q) = a - b x price (P) where a and b are constants. As the price decreases the Quantity (Q) or Demand increases accordingly while the Demand decreases as the price increases.

A demand curve equation is a relation between the price of a good and the quantity demanded for the good expressed as q=f(p) or p=f(q). The price of a good and the quantity demanded are usually inversely related. The exception occurs with Giffin Goods where a price rise can result in increased demand.
