Lecture Notes

The following are lecture notes designed for the College Algebra class at ATU. The topics follow the partition of the textbook "Functions Modeling Change" by Hughes-Hallett et al. These notes have been improved and will continue to be. Please feel free to browse through them.

To Students: BEWARE! The notes posted here are those that I write for myself to bring to class so that if you miss class, you can see approximately what we covered. I will NOT be posting notes as they would appear in class. There will be many missing examples and explanations. This is not a replacement for coming to class and taking notes yourself.
