$8$ $8$

Since we are being asked to evaluate $f (- 2)$ $f(-2)$ , everywhere we see an $x$ $x$ , we replace it with a $- 2$ $-2$ . We now have

$| - 2 | + 6$ $|-2|+6$

NOTE: Absolute Value makes any number positive, so we essentially have

$2 + 6$ $2+6$

which is obviously

$8$ $8$

Hope this helps!
