Question

Describe Absolute Value Function

Answer 1

Absolute Value 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. The absolute value parent function, written as

$f\left(x\right)=\left|x\right|$is defined as.$$\begin{gathered} f\left(x\right)=\left\{x:x>0 \\ 0:x=0 \\ -x:x<0\right\}. \end{gathered}$$

Thus, this is the Absolute value function.
