Describe the general appearance of a demand or a supply curve with infinite elasticity.

Infinite elasticity refers to a situation where even a minuscule change in price leads to an enormous change in the quantity demanded or supplied. This occurs when the price elasticity of demand or the price elasticity of supply is considered infinite.

A demand curve with infinite elasticity appears as a horizontal straight line at a specific price level. No matter how small a price drop or increase, the quantity demanded instantaneously changes to an infinite amount. This situation is also known as perfectly elastic demand.

A supply curve with infinite elasticity also appears as a horizontal straight line at a specific price level. A minuscule change in price leads to an infinite change in the quantity supplied. Just like in the case of demand, this situation is referred to as perfectly elastic supply.

Both the demand and supply curves with infinite elasticity share the following characteristics: 1. Horizontal straight line: The curve is a horizontal straight line at a specific price level. 2. Infinite change in quantity: Even a tiny change in price leads to an infinite change in the quantity demanded or supplied. 3. Perfect responsiveness: The market is extremely sensitive to price changes, with both consumers and producers immediately adjusting the quantities they demand and supply. To summarize, a demand or supply curve with infinite elasticity has a horizontal appearance at a specific price level, and any small change in price leads to an infinite change in quantity demanded or supplied. This reflects perfect responsiveness of the market to price changes.
