# MAT 151 - College Algebra [SUN# MAT 1151]

4 Credits, 4 Contact Hours
4 lecture periods 0 lab periods

Introduction to college-level algebra. Includes functions, exponential and logarithmic functions, linear 2x2 and higher systems, graphing, and calculator use. A graphing calculator is required.

Prerequisite(s): Within the last three years: MAT 095  or MAT 097  or MAT 122 or MAT 122Z or MAT 123 with a grade of C or better, or required score on the Mathematics assessment test.
Information: Credit for only one course will be awarded to students completing MAT 151 and MAT 188 . See course description or advisor to choose your best option. No more than 7 credits may be applied toward graduation from the following list of courses: MAT 151, MAT 182, MAT 187, MAT 188 , and MAT 189 . A graphing calculator is required. See your instructor for details. Access to a scanner required for math classes taken online.
Gen-Ed: Meets AGEC - MATH; Meets CTE - M&S.
