Economics tells us that the demand curve is a graphical representation of how much buyers are willing to purchase at any given price. It’s determined by analyzing the relationship between quantity demanded (Qd) and price (P). In other words, it shows how much people are prepared to buy at different prices; it also allows us to determine what happens when price changes. In short, it’s a crucial tool for understanding market dynamics. As such, business owners can use the demand curve to accurately forecast sales trends, plan marketing strategies, set pricing strategies, and make sound investment decisions.
