• 2011 Contributors: Alex Basyrov, Pangyen Weng, Audrey Battrum, Shumei Richman
• Freshman level college algebra course
• Pre-requisite: Intermediate algebra or 2 years of high school algebra or high enough mathematics placement.

Possible textbooks include, but are not limited to:

• Michael Sullivan and Michael Sullivan III. College Algebra—Enhanced with Graphing Utilities, Fifth Edition. Upper Saddle River, NJ: Prentice-Hall, Inc., 2009.

## Notes on Possible Use of the Problem Sets

• There are probably more problems in the problem sets that one would want to use in a real course. The assumption was that it is easy to remove any problems that one does not want to use.
• Course topics roughly correspond to numbers (01, 02, 03, etc.) in homework sets
• Some of the larger topics are split into smaller subtopics -- in that case there is a letter attached to the number (a, b, c, etc.) to make it homework set 05a, 05b, etc.

## Topics Covered

• Linear Equations
• Lines and Circles and their graphs
• Functions and Their Graphs
• Inverse Functions
• Linear Functions, Their Properties, and Linear Models
