Answer
$(2,-3),(-6,-9),(0,3)$
Work Step by Step
$f(x) = 2x+3$ if $x\leq 0$
$f(x) = -x-1$ if $x\gt 0$
Substituting $x $ value in $f(x) = 2x+3$ if $x\leq 0$ or in $f(x) = -x-1$ if $x\gt 0$
$f(2) = -2-1 = -3$
$f(-6) = 2(-6)+3 =-12+3 = -9$
$f(0) = 2(0)+3 = 0+3 =3$
In Ordered pair $(x,f(x)): $ $(2,-3),(-6,-9),(0,3)$
