In this lesson, you will learn how to graph an absolute value function using a table. The key takeaway is to find the lowest point in the absolute value and pick a point to the left and right of it. Also, be careful with multiplying by fractions as it can be tricky to graph. Once you have your values, simply connect the dots to form the graph of the absolute value function.
How to graph an absolute value function using a table
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.
