$a.\quad 2$ $b.\quad 1$ $c.\quad -1$ and $1$
$a.$ the number in the column $h(x)$ that corresponds to $x=-2$ is $2$ $h(-2)=2$ $b.$ the number in the column $h(x)$ that corresponds to $x=1$ is $1$ $h(1)=1$ $c.$ The number in the column $x$ that corresponds to $h(x)=1$... ...there is $x=-1$, ... and there is also $x=1$, so $h(-1)=1$ $h(1)=1$
