D.
f(x) = |x| – 4

Answer 3

i think its d

Answer 4

It's D. This is a matter of knowing your transformations - if the modification is on the outside you're changing in the Y direction, and it changes they way you would expect. So we want a negative 4 on the outside, which is absolute value of x closed minus four. So D.
