#### Answer

$a.\quad 6$
$b.\quad 12$
$c.\quad 0$

#### Work Step by Step

$a.$
the number in the column $f(x)$ that corresponds to $-2$ is $6$
$f(-2)=6$
$b.$
the number in the column $f(x)$ that corresponds to $2$ is $12$
$f(2)=12$
$c.$
The number in the column $x$ that corresponds to $f(x)=9$ is $0$
$f(0)=9$
