Calculus is a topic that examines how quantities change and accumulate. This is important in business and economics where we are interested in how quantites like revenue, cost, and profit change and accumulate. To understand how this works, we need to familiarize yourself with these functions as well as others like supply and demand. In the beginning of this chapter, we will define these functions and explain how they are related to each other. This will help us to achieve the first goal of this chapter.

- Evaluate, graph and define functions.

Change and accumulation are defined in terms of limits. Limits help us to examine how function behave near a point. Our main goal will be to

- Evaluate limits.

We will use graphs, tables and formulas to accomplish this goal in each of the sections below.

Through the sections below, you learn more about limits in order to prepare you for these important concepts in calculus.

Section 1 – Functions

Section 2 – Basic Concepts of Limits

Section 3 – Computing Limits Algebraically

Section 4 – Computing Limits at Infinity

Section 5 – Continuous Functions

The PDF below contains the answers to the workbook practice problems in each section.
