# Intermediate Algebra

#### Prerequisites

MTH 65 or equivalent placement test scores; placement into WR 115

## Course Description

Introduces functions graphically and symbolically with an emphasis on function notation. Investigates functions, equations, and graphs involving linear, quadratic, rational, radical, and absolute value expressions. Integrates technology throughout. Graphing calculator required. Prerequisites: MTH 65 or equivalent placement test scores; placement into WR 115. Audit available.

## Intended Outcomes

Upon successful completion of this course, students will be able to:

1. Formulate and solve problems in one variable using quadratic, rational and radical equations as models.
2. Formulate and solve problems in one or more variables using linear models.
3. Recognize the connection between graphs and algebra and solve problems both symbolically and graphically.
4. Recognize the graph of a function and use function notation.
5. Communicate results mathematically and in writing.

## Outcome Assessment Strategies

Instructors will use a variety of the following measures:

• Homework, quizzes, group activities, problem sets
• Exams, which may include: proctored, take-home, open-book, group, cumulative.
• Projects, portfolios, and field work - individual or group

## Course Activities and Design

This course will be delivered through a combination of lecture and student activities including group and individual problem solving during class. Emphasis is to be given to applications from outside the mathematics classroom. At least 2 hours per week must be set aside for students to work problems in class.
