    Math Paper 12 May/June 2013

    i hope im not freaking anyone out, but i found the test really easy, as for Q7 it was a bit tricky, but if you drew a graph you would've found it a bit easier, although the question said by calculation which you still had to do

    AS maths pastpaper question help!

    ok, first find the vertex (-b/2a) x=2,y=2 now substitute these values in complete square form a(x-x)^2 + y, which becomes 2(x-2)^2 +2, from here its much easier to get an inverse since all you have to do is send everything (except for x) to the other side, becomes = (y-2/2)^.5 +2, and good luck...
