## 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
- Quadratic Equations
- Equations Quadratic In Form
- Radical Equations
- Lines and Circles and their graphs
- Functions and Their Graphs
- Inverse Functions
- Linear Functions, Their Properties, and Linear Models
- Quadratic Functions and Their Properties
- Inequalities Involving Quadratic Functions
- Polynomial and Rational Functions
- Exponential Functions
