Absolute Value Introduction The absolute value of a number is its value, or magnitude, without respect to sign.

If we map both those possibilities on a number line, it looks like this: This notation tells us that the value of g could be anything except what is between those numbers.

A quick way to identify whether the absolute value inequality will be graphed as a segment between two points or as two rays going in opposite directions is to look at the direction of the inequality sign in relation to the variable.

Identifying the graphs of absolute value inequalities If the absolute value of the variable is less than the constant term, then the resulting graph will be a segment between two points.

If the absolute value of the variable is more than the constant term, then the resulting graph will be two rays heading to infinity in opposite directions.

The dog can pull ahead up to the entire length of the leash, or lag behind until the leash tugs him along.

He cannot be farther away from the person than two feet in either direction. In other words, the dog can only be at a distance less than or equal to the length of the leash. The constant is the maximum value, and the graph of this will be a segment between two points.

Imagine a high school senior who wants to go to college two hours or more away from home. There is no upper limit to how far he will go. The constant is the minimum value, and the graph of this situation will be two rays that head out to negative and positive infinity and exclude every value within 2 of the origin.

What can she expect the graph of this inequality to look like? A A ray, beginning at the point 0. C A ray, beginning at the point 0. D A segment, beginning at the point 0.

A ray beginning at the point 0. The correct graph is a segment, beginning at the point 0. Since the inequality actually had the absolute value of the variable as less than the constant term, the right graph will be a segment between two points, not two rays.

This question concerns absolute value, so the number line must show that The range of possible values for d includes any number that is less than 0. Solving One- and Two-Step Absolute Value Inequalities The same Properties of Inequality apply when solving an absolute value inequality as when solving a regular inequality.

The main difference is that in an absolute value inequality, you need to evaluate the inequality twice to account for both the positive and negative possibilities for the variable. The first step is to isolate the absolute value term on one side of the inequality.

We can do that by dividing both sides by 3, just as we would do in a regular inequality.Apr 07, · I've worked with more basic piecewise function using the absolute value function which involve = signs but I have no clue what to do here. If someone could give me an idea of what the following graph would look like that would also caninariojana.com: Resolved.

Take a break. Let's see what else you know. Back to practice. Algebra 1 DD.4 Domain and range of absolute value functions: equations. Hi Timothy, Let me try a different example, x [3, 11]. The absolute value notation for an interval is anchored at the middle of the interval.

The middle of this interval is (11 + 3)/2 = 14/2 = 7. Want to write an equation to translate the graph of an absolute value equation? This tutorial takes you through that process step-by-step!
