Answer (first one):

$-2\leq x\leq 8$

Explanation:

think of f(x) as y.

y>-2

Now find the parts on the x axis that correspond with parts on the y value that are greater than -2.

$x\geq -2 \\x \leq 8$

This would be all of the numbers between -2 and 8 (inclusive).

The reason it is inclusive is because the arrow ends are shaded in.
