Learn to solve and graph absolute value equations, including finding x values and plotting v-shaped graphs for positive and negative cases.

Understand why an absolute value equation can have from 0 to 2 solutions. Solve absolute value equations with different numbers of solutions. Created by Sal Khan.

To solve absolute value equations, find x values that make the expression inside the absolute value positive or negative the constant. To graph absolute value functions, plot two lines for the positive …

Doesn't matter what x you put in there, when you take its absolute value, you're going to get a value that's greater than or equal to 0. So there's no x that you could find that's somehow-- you put it there, …

You can't take the absolute value of the individual parts. We follow PEMDAS rules. The absolute value is a special case of parentheses. We do the work inside the parentheses 1st. The absolute value gets …

So if I take the absolute value of something and I got you 1/7, there's two possible things that I took the absolute value of. I could have taken the absolute value of positive 1/7, or I could've taken the …

This topic covers: - Solving absolute value equations - Graphing absolute value functions - Solving absolute value inequalities

Any value of "x" will still create a positive value on the side with the absolute value. If you choose to solve the inequality, you would do the following steps:
