Polynomial function:

Polynomial functions are of the form [br][br][math]f\left(x\right)=a_nx^n+a_{n-1}x^{n-1}+...+a_1x+a_0[/math][br]where[math]a_n,a_{n-1},...,a_0[/math] are constants, and [math]n[/math] is a positive integer[br][math]a_n\ne0[/math][br]The degree of a polynomial is[math]n[/math] , which is the highest power of [math]x[/math] in the function.[br]They can be categorized into two types: odd power function and even power function.
Example of even power polynomial function:
Quadratic function, [math]n=2[/math]
Example of Odd Power Polynomial Function:
Cubic function, [math]n=3[/math]
