Answer
$G$
domain: $(-\infty, +\infty)$
range: $[0, \infty)$
Work Step by Step
The graph of the absolute value function $f(x)=|x|$ is V-shaped (refer to page 252 of the textbook).
Thus, the graph of $f(x)=|x|$ is the one in Option $G$.
The graph covers all x-values so the domain is $(-\infty, +\infty)$.
The graph covers the y-values from $0$ and above so the range is $[0, \infty)$.
