Definitions:

MC Curve

The MC Curve, or Marginal Cost Curve, represents the change in total cost that arises when the quantity produced is incremented by one unit. It is crucial in determining the optimum production level.

AVC Curve

The Average Variable Cost curve depicts the per-unit variable cost of production as a function of total output.

ATC Curve

The Average Total Cost curve, illustrating how the total cost per unit of output changes with the level of output.

Marginal Output

The additional output that can be produced by adding one more unit of a particular input, while holding all other inputs constant.
