Introduction to Calculus in Economics (continued):
In the previous Problem Set question, we started looking at the cost function C (x), the cost of a firm producing items. An important microeconomics
concept is the marginal cost, defined in (non-mathematical introductory) economics as the cost of producing one additional item.
If the current production level is a items with cost C (x), then e cost of computing ħ additionial items is C (x + h). The average cost of those h items is
(C(x+h)-C(x))
.As we analyze the cost of just the last item produced, this can be made into a mathematical model by taking the limit as h→0, i.e. the
h
derivative C¹ (x). Use this function in the model below for the Marginal Cost function MC (x).
