1. The first column shows a sequence of numbers. Second column shows the first difference. (-6) – (-4) = -2 If the pattern continues, what is the 8 th number in the first column? 1074

2. Polynomial Functions 5-1 Unit Objectives: Solve polynomial equations Identify function attributes: domain, range, degree, relative maximums/minimums, zeros Write and graph polynomial functions Model situations with polynomial functions Today’s Objective: I can describe polynomial functions.

3. Polynomial Function: Standard Form Polynomial: sum of monomials (terms) Degree of a polynomial: highest exponent Standard form: terms arranged by exponents in descending order

4. Classifying Polynomial By its DegreeExamplesBy the number of terms DegreeName# of termsName 0 1 2 3 4 5 n Constant Linear Quadratic Cubic Quartic Quintic n th degree Monomial Binomial Trinomial polynomial of n terms Write in standard form. Classify by degree & Terms quartic polynomial of 4 terms 1 2 3 n
