Overview Zeros of functions

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.

Questions answered by this video:
  • How are the number of zeros connected with a polynomial of the nth degree?
  • When is x=a a zero of a function?
  • What happens at the turning point of a graph?

    The statement ' x=a is a zero of function f'should follow with 'only if' 'x=a is a solution of function f(x)=0 i.e.f(a)=0 then the other conclusions => (x-a) is a factor of f(x) and => (a,0)is an x-intercept of the graph are true conclusions.
