Lesson Summary:

In this lesson, you will learn how to determine when a graph is increasing and decreasing. The key is to pay attention to the direction the graph is going and the points where it changes direction or where the arrows are heading towards positive or negative infinity. By doing this, you can identify the points where the graph is increasing or decreasing, and understand how the values of the graph are changing.

Lesson Description:

How to determine when a graph is increasing and decreasing

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.
