What is Polynomial Function ?
Polynomial Function is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). it can be express in a generic form as shown below.
How to Graph ?
You can graph any polynomial functions by both hands(harder method) and technology(easier method).
When graphing with hands, you need to know the xintercepts(also known as roots), yintercept, and end behaviours of the function. Some of the tips you can use for drawing by hands are
< Quadrant on a Cartesian Coordinate >
Descartes rule of signs
This rule is used to identify the number of positive roots, negative roots, and/or imaginary Roots of a polynomial function. By the application of this rule, you can identify whether you found the correct roots or not.
Even and odd functions
Odd function is an odddegree function with a point symmetry, proved by f(x)=f(x), x can be any real numbers
Even function is an evendegree function with a line symmetry, proved by f(x) = f(x), x can be any real numbers
Polynomial Division
