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.
