The gradient or "k" was 2.5. I left it at 1.25 but was supposed to multiply it by 2. Can't remember the inverse of f but it was the cube root of x minus something followed by -2. All in all was a splendid paper. Though I did make errors where I shouldn't have, I still expect a 64, which should make the threshold for this paper, which I expect to be in the late 50's for A*.
(x-3)-2, i think
