Lesson Summary:

In this lesson, we learn how to simplify the difference quotient. By breaking down the steps, we see how to evaluate a function at a point h units away from x. We simplify the difference quotient by factoring and expanding the equation, then canceling out variables to get our final answer. With a little bit of practice, simplifying the difference quotient can be easy and straightforward.

Lesson Description:

Simplifying the difference quotient

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.
