Introduction

The Algebra I course covered linear, quadratic, exponential & polynomial functions. In this section we will further explore polynomial functions. A polynomial is composed of multiple terms that contain positive integer exponents.
5x2 - 2x is a polynomial.

3x2 - 2x-2 is not a polynomial because it has a negative exponent.

 \sqrt{x-1} is not a polynomial because it has a variable under the square root.

 \frac{5}{x^{3}+1^{}^{}} is not a polynomial because it has an exponent in the denominator of a fraction.

4x^{0.3} is not a polynomial because it has a decimal exponent.
