Been ages since I've been here. At any rate, I need some serious help here. Ok, its from puremaths paper-4, may/june 2009. The questions are attached. And in case you can't get the attchments, well they are questions 5 and 6 from the questions paper. I'm having problems specifically in 5)ii and iii. And in 6)ii, iii and iv.

Okay If I have any more problems I'll write em down. Thank you.

Hey thanks astar!
Thanks a lot.

Hmm, that makes sense I guess,though the answers to the first two parts don't match but that's because of a calculation error. But the way you did it is correct. So kudos to you! But dude like where is the answer to number 6? The pdf file entitled number 6 has the same thing as in the other one.  Could you please submit that then?
Thanks again
:)

Oh and I have some problems in finding the range and domain of functions and completing the square...help pleeease

=_=
