What are polynominal function? Can you please explain in a easy way to understand thank you

A polynomial function is a relationship that provides a value that is determined by a polynomial for each input value.

Explanation:

A polynomial is a mathematical expression constructed with constants and variables using the four operations:

Linear2x+11

Quadratic3x2+2x+12

Cubic4x3+3x2+2x+13

Quartic5x4+4x3+3x2+2 x+14

In other words, we have been calculating with various polynomials all along. When two polynomials are divided it is called a rational expression.

In such cases you must be careful that the denominator does not equal zero. Division by zero is not defined and thus x may not have a value that allows the denominator to become zero. Otherwise, any other value may be substituted for x.

Example

x3−x6−x

x must not have the value of 6 since 6-6=0.
