Title of Lesson: Polynomial Functions of Higher Degrees

By the end of this lesson, I will be able to answer the following questions1. How do I sketch graphs of polynomial functions using intercepts, end behavior and strategic points?

2. How do I build functions using intercepts and clues?

3. How do I Build polynomials functions given a real-world scenario and analyze the results using a graphing calc.

4. What is the Intermediate Value Theorem and what is it used for?

Vocabulary1. Multiplicity: Repeated zeros of a function

2. Intermediate Value Theorem: Let a and b be real numbers such that a < b and there is some value c which is on the interval [a,b] that guarantees

Prerequisite Skills with PracticeCalculator discovery:Monomials of higher degrees(use different colors)

Properties ofPolynomial graphs

They are always Continuous, that is they have no breaks

They are smooth and rounded no sharp turns

They have predicable endbehavior.
