Below

Explanation:

For zeroes, let $y = 0$ $y=0$
$0 = | x + 4 |$ $0=abs(x+4)$
$0 = x + 4$ $0=x+4$ or $- (x + 4) = 0$ $-(x+4)=0$
Since both equations will get me the same value, I'll use $0 = x + 4$ $0=x+4$

$x + 4 = 0$ $x+4=0$
$x = - 4$ $x=-4$

For intercepts, let $x = 0$ $x=0$
$f (0) = | 0 + 4 |$ $f(0)=abs(0+4)$
$f (0) = 4$ $f(0)=4$

Domain: all reals $x$ $x$
Range: $y \geq 0$ $y >=0$
