The expression that is not a polynomial is [tex]\frac{x^{2} - x - 12 }{x + 3}[/tex]
A polynomial function is a function that is made up of non-zero coefficients, positive exponents, and constants.
Types of polynomials
1. Linear polynomial function: it is made up of one variable raised to the power of 1.
An example is y + 10
2. Quadratic polynomial function - it is made up of a variable that is raised to the power of two.
An example is x² + 10x + 25
3. Cubic polynomial function: a single power is raised to the power of three.
An example is 124y³ + y²
The following are not polynomials:
- An expression that is divided by another variable.
- An expression with a negative exponent
- An exponent that is a decimal.
