Find the Domain and Range x=|y|

$x = | y |$

The domain is the set of all valid $x$ values. Use the graph to find the domain.

$[0, \infty)$

${x | x \geq 0}$

The range is the set of all valid $y$ values. Use the graph to find the range.

Interval Notation:

$(- \infty, \infty)$

Set-Builder Notation:

${y | y \in ℝ}$

Determine the domain and range.

Domain: $[0, \infty), {x | x \geq 0}$

Range: $(- \infty, \infty), {y | y \in ℝ}$
