    then there was the differentiation wasn't there...

    of something to get 4x^3 - 16x = dy/dx

    then you had to show that at x = -3 it was a minimum...
    so d2y/dx2 = 12x^2-16
    12(-3)^2-16
    = 92
    > 0 therefore min at x=-3

    In this question "The transformation of [2 -0.7] was √((x-2)3 +1) -0.7" I made a stupid mistake and put "-1" rather than "+1". How many marks will I lose and will I get follow through marks when working out G(4)?

    for the binomial with x^-2 i let y become this throughout all of the simplifying and expanding and then switched at the end to get (x^-2)^2 and the number before but i cant remember what that was would this still be right

    I'm thinking...

    Looking at past boundaries

    C1: (on the easy side)
    A 63
    B 57
    C 51
    D 45
    E 39

    C2: (was tricky, but nothing horrendous - average)
    A 58
    B 51
    C 45
    D 39
    E 33

    but.. I am guessing... haha

    This is all I want to know:

    For core 1

    Integration question:
    Area under curve was 524/15
    Shaded area was 961/15

    Final question:
    20/7 <= k <= 4

    Correct or not...?

    I got the same answer for the integration, but most people seem to have got 27. I think we might have mad a mistake somewhere.
