    On the earlier question of (25/9)^-1/2 I only put 3/5 instead of + or -
    I'll probably lose a mark won't I
    No powers only have one value bro

    But it's a square root so wouldn't it be + or -?

    No, to the power of 1/2 means the positive square root

    Can someone please tell me how many marks I would lose on that question and follow on questions for putting the minimum point as (-2,9) and so the complete the square bit as 3(x+2)^2+9????

    Ah nice hopefully I'll lose less marks than I thought then! Still annoyed I got the proof wrong for x^2 is an integer <-> x is an integer. Such a silly mistake

    Not many and certainly not many year 12s so grade boundaries take that into account

    No it isn't necessary unless you are doing the quadratic formula

    No, the mark schemes say ignore +- for those questions

    Stress. Would you have said that c was 13+k
    When k>14/3
    I'm confused by what you mean?
    Seen as it was a positive parabola surely it would have to be k>something for 2 intersections!
