Definitions:

Marginal Cost Curve

A graphical representation that shows how the cost of producing one more unit of a good varies as the quantity of production increases.

Average Cost Curve

A graphical representation that shows how the cost per unit of producing a good changes with changes in the volume of output.

Cost-output Elasticity

Cost-output elasticity measures the responsiveness of production costs to changes in the quantity of output produced, indicating how cost-efficiently a firm can adapt to changes in production volume.

Long-run Cost Function

Refers to a firm's costs of production when all inputs, including capital, are variable and can be adjusted.
