Topic #5 Polynomial Functions
Topic 5 ObjectivesAfter completing the topic Polynomial
functions, students will be able tounderstand the relationship between the degree
of a polynomial and the number of real zeros it has, as detailed in the Fundamental Theorem of Algebra and related theorems;
understand the relationship between the degree of a polynomial function and the number of local extreme values of the function;
describe the end behavior of polynomials of odd and even degree.
Topic 5 Vocabulary (due next Friday)periodic function, degree of a polynomial, absolute or global maximum or
minimum, local maximum or minimum, interval notation, long-term or end behavior, zeros of a function

each function and describe the end behavior.
