# MATH 128 - College Algebra

Credit Hours: 3
Lecture Hours: 3 or 4
Laboratory Hours: 0

Prerequisite(s): Permission of the instructor required for extended contact hour sections

Restriction(s): None

Corequisite(s): None

This course begins with a review of Elementary Algebra topics: fractions, order of operations, exponents and polynomials, one-variable linear equations. The central theme of the course is a study of functions, using both graphic and algebraic methods. The functions we will focus on are: linear (with slope studied as a rate of change), quadratic, exponential, and logarithmic. “Real world” applications of these functions are considered. Students are expected to use a scientific calculator for all aspects of the course. Other technology may be incorporated at the instructor’s discretion.

Student Learning Outcomes of the Course: GENERAL EDUCATION STUDENT LEARNING OUTCOMES:

1. Students will demonstrate the ability to interpret and draw inferences from mathematical models such as formulas, graphs, tables, and schematics
2. Students will demonstrate the ability to represent mathematical information symbolically, visually, numerically and verbally.
3. Students will demonstrate the ability to employ quantitative methods such as, arithmetic, algebra, geometry, or statistics to solve problems.
4. Students will demonstrate the ability to estimate and check mathematical results for reasonableness.
5. Students will demonstrate the ability to recognize the limits of mathematical and statistical methods.

COURSE-SPECIFIC LEARNING OUTCOMES:

1. Students will be able to solve linear, quadratic, exponential, and logarithmic equations in one variable.
2. Students will be able to classify linear, quadratic, exponential and logarithmic functions from their formulas and from their graphs.
3. Students will be able to predict the behavior of linear, quadratic, exponential and logarithmic functions (such as increasing/decreasing, intercepts, etc.) based on their parameters.
4. Students will be able to solve a system of equations in two or three variables using the addition/elimination method.
5. Students will be able to apply linear, quadratic, exponential and logarithmic functions and systems of equations in “real world” situations.
