How do you find the domain of f(x)=abs(x+4)?

Aug 8, 2018

Domain: $x \in \mathbb{R} \mathmr{and} x \in \left(- \infty , \infty\right)$

Explanation:

$f \left(x\right) = \left\mid x + 4 \right\mid$ , domain is possible input of $x$, here , any

real value of $x$ as input for which #f(x) is defined.

Domain: $x \in \mathbb{R} \mathmr{and} x \in \left(- \infty , \infty\right)$

Range : $f \left(x\right) \ge 0 \mathmr{and} f \left(x\right) \in \left[0 , \infty\right)$
