PPT-Section 5.1 – Polynomial Functions

Defn Polynomial function In the form of   The coefficients are real numbers The exponents are nonnegative integers The domain of the function is the set of all real numbers. Objectives: Identify Polynomial functions. Determine end behavior recognize characteristics of polynomial functions. Use factoring to find zeros of polynomial functions.. Polynomials of degree 2 or higher have graphs that are smooth and continuous. By smooth we mean the graphs have rounded curves with no sharp corners. By continuous we mean the graphs have no breaks and can be drawn without lifting your pencil from the rectangular coordinate system.. Algebra II with . Trigonometry. Ms. Lee. Essential Question.
