Virtual Nerd: What Is an Absolute Value Function?

What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign.  They graph each function on a coordinate plane and identify the maximum and...

One of the strongest tools an algebra learner develops is the ability to quickly and accurately graph almost any given function. Often doing this quickly and accurately requires rigid transformations to a parent function,...

Sal demonstrates how to solve an absolute value equation, keeping in mind there are two possible answers.

Sal reviews absolute value equations by taking viewers through a careful and deliberate problem-solving process. Those who didn't thoroughly understand absolute value during class will appreciate Sal's steady and straightforward...

Combining the skills from the previous videos, particularly inequalities and absolute values, Sal works to solve several new sample problems. He encourages watching the video "over and over," which is good advice for mathematicians of...

The sole purpose of this interactive is to graph a function representing the distance of a car from a shoe store. Scholars use an interactive to graph such an absolute value function. They then answer a set of challenge questions...

Absolute value is basically the distance between "number" and "zero" on a number line. You will learn more about this concept in this video. You will also learn how to express absolute value functions as piecewise functions. [10:47]

Translate an absolute value equation, horizontally and vertically. First, what is the form of an absolute value equation? There are several variables that represent specific pieces in this equation. Vertical, horizontal, constant,...

Using this tutorial, you'll learn how to solve absolute value equations. View step-by-step solutions and video explanations of example problems, and solve practice questions at the end.

Use this word problem to practice turning words into math. You'll follow the step-by-step process to determine what is being asked and what you'll need to do to solve the problem. A great tutorial for learners needing a little extra help...
