19 Polynomial Function Functions defined by polynomial expressions are called polynomial functions Polynomial functions are easy to evaluate because they are defined using only addition, subtraction, and multiplication

21 If a polynomial consists of just a single term, then it is called a monomial.

22 The graph of a polynomial function is always a smooth curve; that is, it has no breaks or corners.
