F) $(9, \infty)$
G) $(-\infty, 0]$
H) $[-9, \infty)$

Question

Quizplus · Accepted Answer

The domain of any absolute value function, including $f(x) = |x-9|$, is all real numbers, which is represented by the interval notation $(-\infty, \infty)$. This is because you can input any real number into the function and get a real number output.
