Question

URGENT PLEASE HELP Definitely need the correct answers as I am failing precalculus

Answer 1

Answer (first one):

${x|-2\leq x\leq 8}$

Step-by-step 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.
