In this lesson, the instructor teaches how to graph a polynomial function by finding the zeros and using the leading coefficient test. The first step is to find the zeros, which are x-intercepts, by setting f and x equal to zero. After factoring, the zeros can be found and plotted on the graph. The instructor also discusses the use of the intermediate value theorem to find additional points between the intercepts. By understanding the leading coefficient test and end behavior, graphing a polynomial function can be done easily and accurately without a calculator.
Using end behavior, zeros and the intermediate value theorem to graph a polynomial
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.
