A cost curve is a graphical representation of the relationship between production costs and the quantity of output produced. The cost curve can be used to show how changes in production costs will impact the quantity of output produced by a firm. Additionally, the cost curve can be used to show how different firms produce different quantities of output at different costs.

The cost curve is downward sloping, which means that as firms increase production, they will experience economies of scale and their per unit costs will decrease. The steeper the slope of the cost curve, the greater the economies of scale experienced by firms. The economics principle of diminishing returns dictates that eventually, as firms continue to increase production, they will reach a point where their per unit costs begin to rise. This point is represented by the point of diminishing returns on the cost curve.

In order to maximize profits, firms will produce at the quantity where their marginal revenue equals their marginal cost. This quantity is represented by the intersection of the marginal revenue curve and the marginal cost curve.
