# MATH 098 Essentials of Intermediate Algebra • 5 Cr.

## Department

## Division

## Description:

Reviews and expands MATH 097 topics for students with some algebra background. Topics include equations of lines, quadratic equations and parabolas, rational exponents, elementary exponential equations, and elementary rational expressions and equations. Students practice model building and analysis of graphical and numerical data. Prerequisite: Placement by assessment, or MATH 085 or MATH 097 with a C- or better.
