  • Department:


  • Credits:

    1.0 (yearlong course)

  • Prerequisites:

    Algebra 2 (MATH300) or equivalent



Not returning for 24-25

This course will cover topics common to most traditional pre-calculus courses such as the following: graphs, linear and quadratic functions, polynomial & rational functions, exponential & logarithmic functions, trigonometric functions, analytical trigonometry, polar coordinates & vectors, systems, and sequences. It also incorporates topics including probability & statistics.

Applications to real-world events and graphing calculators are extensively woven into the course.

Special Notes:

This course does not prepare students for AP Calculus. If you plan to take MATH500, you will need to register for MATH450.

The recommended sequence for students taking non-Honors courses: MATH100, MATH200, MATH300 followed by their choice of MATH310, MATH410, MATH420, MATH440, or MATH510.

Students need access to a scanner or digital camera (phone is fine) in order to submit work for the teacher to review. Students will also need a TI-84 graphing calculator for this course.


In this course, we are going to weave together many concepts of functions that you have already studied in Algebra and Geometry and dig a little deeper with them. We will focus on mastering skills you already know and building on them with new skills to help prepare you to be successful in higher level mathematics. Throughout the course, we will learn to apply concepts learned and make connections with them to real life situations. We will be visualizing functions in a whole new way to better understand and investigate the world around us. This course will help prepare you for College Algebra or a college-level PreCalculus Course.

If there are books and materials for this course, they can be purchased from our Online Bookstore.
