You will have to make two graphs, depending on wheter $x$ is negative or not:

$x<0$
The absolute bars will make it positive, so in fact we are now looking at $f(x)=-x+4$

$x>=0$
Nothing needs to be do, so it's $f(x)=x+4$
graph{|x|+4 [-13.86, 14.62, -3.23, 11.01]}

How do you graph f(x) = |x| + 4f(x) = |x| + 4?
