What does a supply curve represent?

A supply curve represents the relationship between price and quantity supplied. It visually demonstrates how the quantity of a good or service that producers are willing to sell changes in response to varying prices. Typically, this relationship is positive, meaning that as prices increase, the quantity supplied also tends to increase. This is due to the fact that higher prices can make production more profitable, incentivizing producers to supply more of the good.

Understanding the supply curve is crucial for analyzing market behavior, as it helps predict how suppliers will react to changes in market conditions, such as shifts in demand, production costs, or government policies. Thus, the supply curve is a fundamental concept in economics that illustrates the dynamics of supply in the marketplace.

The other concepts, such as consumer preferences, total goods available, or production costs, do not define the specific relationship that a supply curve illustrates, making them less relevant in this context.
