D. –19

Answer 1

i got -5 but i just wanna be sure

Answer 2

f(x) = |x+7|; If you know anything about absolute value, you'll know it's never negative. So A and D are out of the answers right away.

Now just plug in -12 for x and you're good to go.

f(-12) = |-12 + 7|
f(-12) = |-5|
f(-12) = 5 (C) <------------Answer

Answer 3
