Title of Lesson: Polynomial Functions of Higher Degrees

By the end of this lesson, I will be able to answer the following questions… 1. 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?

Vocabulary 1. 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 Practice Calculator discovery: Monomials of higher degrees… (use different colors)

Properties of Polynomial graphs They are always Continuous, that is – they have no breaks They are smooth and rounded – no sharp turns They have predicable end behavior.
