# What type of function is absolute value?

Term | Definition |
---|---|

Absolute Value | The absolute value of a number is the distance the number is from zero. Absolute values are never negative. |

Absolute value function | An absolute value function graphs a V shape, and is in the form y = |x|. |

Similarly, can an absolute value be a function?

An absolute value function is a function that contains an algebraic expression within absolute value symbols. Recall that the absolute value of a number is its distance from 0 on the number line. To **graph** an absolute value function, choose several values of x and find some ordered pairs.

Beside above, why is the absolute value function important? Because the **absolute value** of a number is that number's distance from zero, all of the **function values** of an **absolute value function** will be non-negative. As you can see in the graph below, the **absolute value function** forms a “V” shape. There are two **important** things to note about the graph of this kind of **function**.

Likewise, what are absolute value functions used for?

The **absolute value function** is commonly thought of as providing the distance the number is from zero on a number line. Algebraically, for whatever the input **value** is, the output is the **value** without regard to sign. Knowing this, we can use **absolute value functions** to solve some kinds of real-world problems.

What is the absolute value of 20?

The symbol for **absolute value** is to enclose the number between vertical bars such as |-**20**| = **20** and read "The **absolute value of -20** equals **20**".
