Use what we've already talked about...since it's > 4, it is going *away* from 0...

anonymous · Answer

so it would be C

anonymous · Answer

C is *towards* 0...which one is *away* from 0?

anonymous · Answer

it wouldnt be a,b, or d.... so it has to be E

anonymous · Answer

There you go! :)  Now you've got it.

anonymous · Answer

Remember...if it's *away* (>) you'll get 2 disjoint sets (the answer will have two inequalities and the word "or").  If it's *towards* (<) you'll get one comined inequality.

Other than that, you're now a master at this.
