The document discusses polynomial functions. It defines a polynomial function and distinguishes it from other function types. It lists the objectives of understanding degree, using theorems to determine factors and roots, and approximating graphs of polynomial functions. Key points are that every polynomial equation has at least one real or complex root based on the Fundamental Theorem of Algebra, and that a polynomial of degree n will have n roots.
