**Course Description**:

This course is delivered in Lumen OHM with automated grading of numerical and algebraic answers, similar to WebAssign and MyMathLab. This makes it appropriate for self-study by students, or as a face to face course. This course can be imported into your LMS (Blackboard, Canvas, Moodle) to provide a single-sign on experience for your students, as well as grade return for you.

This course covers material traditionally taught in either Precalculus I or College Algebra courses. Specific topics include a review of fundamental algebra skills, followed by an introduction to relations and functions. Four chapters of the text focus on the study of specific functions, their graphs, intercepts, and transformations. Linear, quadratic, polynomial, rational, exponential and logarithmic functions are included in this study. Additionally modeling with functions and attention to using technology to explore specific characteristics of functions are addressed. The last three chapters of the text focus on conics, systems of equations and sequences.

### Text

The text for College Algebra was written by Carl Stitz and Jeff Zeager. This text is a favorite amongst post-secondary math instructors based on it’s elegant delivery of mathematical topics delivered with a twist of humor.

While the authors would like nothing more than to delve quickly and deeply into the sheer excitement that is Precalculus, experience has taught us that a brief refresher on some basic notions is welcome, if not completely necessary, at this stage.
