__Unit Overview:__Students apply properties of number systems to equations to a variety of functions (polynomial, rational, radical, and absolute value), sketch graphs, and identify the zeros of polynomials. Students find patterns to identify polynomial identities and geometric series.

__Enduring Understanding:__- Equations can be manipulated and presented in a variety of equivalent ways; the understandings and operations from rational expressions can be extended to functions of equations.
- The zeros of a polynomial can be found through a multitude of methods.
- Polynomials can be sketched from identifying key elements

Essential Question:

- What is the purpose of graphing functions?
- How can we interpret extraneous solutions?
- Why are zeros of a function important?
- How can identifying patterns be beneficial?
