See the graph and explanation below.

Work Step by Step

We are given the equation: $f(x)=|x|-4$ We plug in a few $x$ coordinates into the given equation to determine the corresponding $y$ coordinates: Plug in $x=0$: $f(0)=|0|-4=-4$ Plug in $x=4$: $f(4)=|4|-4=0$ Plug in $x=-4$: $f(-4)=|-4|-4=0$ Thus, we plot $(0,-4)$, $(-4,0)$, and $(4,0)$. We connect the resulting points with lines to produce the final graph.
