Intro to absolute value equations and graphs - Khan Academy
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 …
Absolute value and number lines (video) | Khan Academy
One easy way to think of absolute value is the distance it is from zero. To do that, a number line comes in handy. Watch and learn. Created by Sal Khan and Monterey Institute for Technology …
Intro to absolute value inequalities (video) | Khan Academy
To solve inequalities with absolute values, use a number line to see how far the absolute value is from zero. Split into two cases: when it is positive or negative. Solve each case with algebra. …
Placing absolute values on the number line - Khan Academy
In this math lesson, we learn to sort values from least to greatest using a number line. We practice with negative numbers, positive numbers, and absolute values. By plotting these values on the …
Graphing absolute value functions (video) | Khan Academy
We can graph any absolute value equation of the form y=k|x-a|+h by thinking about function transformations (horizontal shifts, vertical shifts, reflections, and scalings).
Absolute value as distance between numbers - Khan Academy
No, it does not always have to be on a number line; this is showing you how to do this if you don't have a number line. Since you know you can subtract the number further on the left on the …
Comparing absolute values on the number line - Khan Academy
In this math lesson, we explore absolute values and inequalities using a number line with three numbers: a, b, and c. We determine the truth of four inequalities: a < b, |a| > |b|, |a| < |c|, and a …
Graphing two-variable inequalities (video) | Khan Academy
Understand the absolute value: The absolute value of a number is its distance from zero on the number line, regardless of direction. Therefore, |x - 3| = 2 means that the distance between x …
Solving absolute value inequalities 1 (video) | Khan Academy
Let me draw it on the number line, which they want us to do anyway. So if this is the number line right there, that is 0, and we draw some points, let's say that this is 7, that is 8, that is negative …
Absolute value graph and function review (article) | Khan Academy
The general form of an absolute value function is f (x)=a|x-h|+k. From this form, we can draw graphs. This article reviews how to draw the graphs of absolute value functions.
