1. Algebra II 4.1: Graphing Polynomial Functions Objective: To identify polynomials, and to use several techniques to get rough sketches.

2. Vocabulary • What is a monomial? • An expression that is either a number, a variable, or the product of a number and one or more variables

3. Vocabulary • What is a Polynomial? • A monomial or a sum of monomials

4. A polynomial function is in standard form when its terms are written in descending order of exponents from left to right.

5. Vocabulary • Polynomial Function = a function in the form: n is the degree or the highest exponent. is the leading coefficient. is the constant term.

6. the exponents are all whole numbers • What is a whole number? • the coefficients are all real numbers • What is a real number?

7. Common Polynomial Functions

9. Example 1

10. Decide whether the function is a polynomial function. If so, write it in standard form and state its degree, type, and leading coefficient.
