### Important Concepts for This Unit

Functions defined by polynomial expressions are called polynomial functions. The graphs of polynomial functions can have many peaks and valleys; this makes them suitable models for many real-world situations. The standards that will be assessed in this chapter are

3.2 Can graph polynomials using intercepts, end behavior, root multiplicity, and transformations.

u3.1 - Quadratic Functions and Models

• Obtaining the exact coordinates of the vertex by completing the square.
• Finding roots using the quadratic formula.

u3.2 - Polynomial Functions and their Graphs

• The terminology and notation associated with polynomial functions.
• Characteristics of polynomial graphs: smoothness, continuity, end behavior, and boundaries on the number of local maxima and minima.
• Graphing polynomials using the zeros (taking into account multiplicity) and end behavior.

u3.3 Dividing Polynomials

• The division algorithm for polynomials.
• Synthetic division.
