## 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 technology required – contact instructor for more details. Prerequisites: MTH 65 or equivalent placement; placement into WR 115. Audit available.

## Course Outcomes

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

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

## Suggested 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

The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.
