- The absolute value graph depicts the distance of a number from the origin.
- The graph of the absolute value function is symmetric about the y y -axis.
- The graph of the absolute value function makes a right angle at the origin.
- Absolute value function is an even function because f(x) = f(−x) f ( x) = f ( − x).

How do you graph absolute value on a graphing calculator?
with absolute value, the positive domain of x would be the same as f (x) = x and the negative domain of x would be the same as f (x) = - x. This creates the V shape of absolute value.

How do you calculate absolute value?
Square both coefficients.
- Coefficients: (3, -4)
- Distance formula: 3 2 + ( − 4) 2 {\displaystyle {\sqrt {3^ {2}+ (-4)^ {2}}}}
- Square the coefficients: ' 9 + 16 {\displaystyle {\sqrt {9+16}}}
- Note: Review the distance formula if you're confused. Note now squaring both numbers makes them positive, effectively taking absolute value for you.
How to solve absolute value?
- Find boundary points by solving ∣ x − A ∣ = B \displaystyle |x-A|=B ∣x − A∣ = B.
- Test intervals created by the boundary points to determine where ∣ x − A ∣ ≤ B \displaystyle |x-A|\le B ∣x − A∣ ≤ B.
- Write the interval or union of intervals satisfying the inequality in interval, inequality, or set-builder notation.
What Is an Absolute Value Graph?
The graph of an absolute value function is called an absolute value graph.
How to Vertically Shift Absolute Value Function on a Graph?
Let the equation of absolute value function be f (x) = |x| f ( x) = | x |.
Solved Examples
Frank took three positive x x values to plot the graph of the function given by f 1(x) = |x+2| f 1 ( x) = | x + 2 |
Let's Summarize

1. How do you graph a double absolute value function?
Follow the steps mentioned below to plot a graph of the double absolute value function.
2. How do you graph an absolute value inequality with two variables?
The primary thing to remember while plotting graphs for absolute value inequality is that the graphs of absolute value are "V" shape.
Absolute Value Function
The absolute value of a number is the distance between that number and zero. For instance, the absolute value of 7 is 7, the absolute value of -5 is 5, and the absolute value of 0 is 0. Symbolically, this is written with two vertical brackets around the number: {eq}|7| = 7, |-5| = 5, |0| = 0 {/eq}.
Absolute Value Function Transformations
As seen in the previous section, the absolute value function has a V shape. While this function can be transformed by moving it, reflecting it, or stretching it, its shape will always remain the same. For instance, consider the slightly altered function: {eq}g (x) = 2|x| {/eq}.
How to Graph Absolute Value Functions
As shown above, the parent function of all absolute value functions is the function {eq}f (x) = |x| {/eq} and can be thought of in two pieces: {eq}y = x {/eq} on the right half of the coordinate plane and {eq}y = -x {/eq} on the left half of the coordinate plane.
How To Create an Absolute Value Graph
Absolute value graphs are linear representations of absolute value functions. These equations are always expressed within absolute value bars. Here is an example:
Breaking Down Absolute Value Functions
Let's explain the rules of absolute value functions. The parent function, or the most basic form, of an absolute value, is:
Analyzing an Absolute Value Graph
Let's analyze the graph of an absolute value function f to determine its vertex, x-intercepts, and whether it opens up or down.
Understanding Absolute Value Graphs
The absolute value of a number represents its distance from 0. Graphing absolute value equations allows us to visually understand this concept in terms of x and y-intercepts. It also teaches us how to determine the vertex of an absolute value function and whether it will be upward or downward-facing.
