looks just like the absolute value only shifted down four units right?

Which do you think?

anonymous · Answer

I am not sure how to do this one.... Can you explain?

igreen · Answer

Well, we just subtract 4 from the absolute value in the 'x', it will give us a y-intercept of -4, which is what this graph has.

anonymous · Answer

You mean ' 2 - 4 '

Wait, I know the answer! I think it's D. !
