$x$	$f(x)$
$-9$
$-8$
$-7$
$0$

1. $f(x)=15-6x$

$x$	$f(x)$
$1$
$2$
$3$
$6$

1. $f(x)=-3-2x$

$x$	$f(x)$
$-3$
$-2$
$-1$
$2$

Explanation:

Step1: Substitute x into $f(x)=x-4$

For $x=-10$: $f(-10)=-10-4=-14$
For $x=-9$: $f(-9)=-9-4=-13$
For $x=-8$: $f(-8)=-8-4=-12$
For $x=-7$: $f(-7)=-7-4=-11$
For $x=0$: $f(0)=0-4=-4$

Step2: Substitute x into $f(x)=15-6x$

For $x=0$: $f(0)=15-6(0)=15$
For $x=1$: $f(1)=15-6(1)=9$
For $x=2$: $f(2)=15-6(2)=3$
For $x=3$: $f(3)=15-6(3)=-3$
For $x=6$: $f(6)=15-6(6)=-21$

Step3: Substitute x into $f(x)=-3-2x$

For $x=-6$: $f(-6)=-3-2(-6)=9$
For $x=-3$: $f(-3)=-3-2(-3)=3$
For $x=-2$: $f(-2)=-3-2(-2)=1$
For $x=-1$: $f(-1)=-3-2(-1)=-1$
For $x=2$: $f(2)=-3-2(2)=-7$
