Definitions:

MC Curve

The Marginal Cost Curve shows the cost of producing an additional unit of a good or service, typically rising as production increases.

Cubic Cost Function

A representation of cost as a cubic function of output, allowing for more complex cost behavior including economies and diseconomies of scale.

Average Variable Cost Curve

A graphical representation showing how the average variable cost of production changes with the quantity of output produced.

Marginal Cost Curve

A curve that illustrates the change in total cost that arises when the quantity produced changes by one unit, typically upward sloping due to increasing marginal cost.
