Answer
1st step (black graph): The parent function: $y=|x|$
2nd step (green graph): Shifted 4 units down. $y=|x|-4$
The x-intercepts are (-4,0) and (4,0).
The y-intercept is (0,-4).
The domain is $(-\infty,\infty)$
The range is $[-4,\infty)$
Work Step by Step
The x-intercepts are all points of a graph when f(x)=0 while the y-intercepts are all points of a graph when x=0.
The domain is a horizontal span from the function's smallest value of x to the function's largest value of x.
The range is a vertical span from the function's smallest value of f(x) to the function's largest value of f(x).
