6. 3.1 Graphs of Polynomial Functions Definition A polynomial function is one that can be written in the form: where n is a nonnegative integer and the coefficients are real numbers. If the leading coefficient is not zero, then n is the degree of the polynomial. State whether the following are polynomials. If so, state the degree.

7. 3.1 Graphs of Polynomial Functions End Behavior End behavior is determined by the degree and the leading coefficient. Create Chart. Number of “Bumps” The number of “bumps” a graph may have is no more than one less than the degree. The number of zeros a graph may have is no more than the number of the degree.
