Credit Hours

3

Prerequisites

MATH 100 with a grade of C- or higher, or Math Placement Assessment.

Description

The study of functions, their graphs, and their basic properties. Emphasis is placed on polynomial functions, including linear and quadratic functions. Computing real and complex roots of polynomials is explored. Additional topics include: the study of rational functions, absolute value functions, and inverse functions; and solutions of systems of equations.
