## Unit 2: Polynomials, Radical, and Rational Relationships

### Overview

*In the Math I and Math II courses, students have mastered linear and quadratic functions. In this unit, the students will extend their understanding of these functions to include relationships among higher-order polynomial functions, radical functions, and rational functions. They will take an in-depth look at polynomials and be able to identify important concepts such as finding zeros, extreme values, points of intersection, and ways to rewrite the functions using strategies such as division, factoring, and expansion. Students will be able to graph these functions using end behavior and zeros, as well as using technology to assist in graphing more complex functions.*
