Graphing a Fourth Degree Polynomial
In this lesson, we learn how to graph a fourth degree polynomial without the use of a calculator. We use the leading coefficient test to determine the n-behavior of the graph, and then find the zeros by setting the polynomial equal to zero and factoring. We also use the intermediate value theorem to find additional points on the graph between the zeros. By using the multiplicity of each zero, we can determine if the graph will touch or cross the x-axis. Finally, we connect the points and use the n-behavior to complete the graph.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
- In g(x)=xâ´-4x² what is the multiplicity of 0?
- What is the behaviour of the graph when the degree is even ?
