Mind posting the question first?  Then I'd be in a better position to respond.

anonymous · Answer

Okay, so this is the part I'm confused on, do I add them first and then change the sum to a positive or do I change the -11 to a positive first, and then add?

By all means combine what's inside the absolute value operator FIRST.

dont mind my hint i was thinking about radicals

anonymous · Answer

Oh.. see, that's what I'm doing wrong.. 
So I add -11 and 8 and I get |-3| which is basically 3.

yeah

anonymous · Answer

Oh, okay, thank you guys! :)

anonymous · Answer

Ok, I worked out this one, did I do it right?|dw:1391841805002:dw|

anonymous · Answer

That looks like it says f-2 it says f=2

mathmale · Answer

I'm having some problems reading what you've typed.  Would y ou please post this as a new question and type the function in as closely following the original problem statement as you can manage.       f-2 is incorrect; I believe you mean f(-2) to indicate "the value of the function f(x) when x=-2"

anonymous · Answer

Ok, I'll put a new question.
