Section 5.2 (DAY 1): Evaluate and Graph Polynomial Functions
OBJECTIVES:
Write a polynomial function in _______________ form and classify it.
Identify the _______ ____________ of a polynomial function.
Use direct substitution to ________ a function for a given value.
Vocabulary:
monomial: a number, variable, product of numbers/variables
polynomial: monomial or sum of monomials
~ Exponents: whole #s (≥0)
~ Coefficients: real #s
polynomial function:
leading coefficient: an (≠0)
degree: n (highest power)
constant term:
a0 (no variable)
Standard form: terms are written in decreasing order of exponents from LEFT to RIGHT
