Word Definition Example
Polynomial functions are named by the number of terms and by degree of the polynomial.
Example 2: Decide if each function is polynomial. If it is a polynomial, write function in standard form, and state the degree and leading coefficient.

Story Problems Multiplying Polynomials
11. What is the volume of the rectangular prism (solid) shown?
We have added, subtracted, or multiplied two or more polynomial functions to build a new polynomial function. When an operation is performed on any number or
expression in a set and the result is the in the same set, it is said to be closed under that operation. Are
polynomials closed under addition, subtraction and
multiplication? In other words, when you add, subtract or multiply polynomial functions, will you always create another polynomial function?
Similarities between integer and polynomial operations are shown in the table.
So which operations are polynomials closed under?
