    3.1 and 14.1 instead of 13.9? is it alright?
    Rounding error I'm guessing? I think you'll drop a mark

    For Q 7c if wrote that you can't have an inverse of a cubic would i have got the mark?
    I think you have to be more specific and explain that it's a many-to-one

    Nope, many-to-one. Several x values match up to one y value. If it was one to many it wouldn't be a function.

    Hi for the reason why the graph can not be an inverse I put that there can not be an inverse as the graph cannot be a function since it is a one to many? Is this wrong?

    [QUOTE=paradoxicalme;56927209]Rounding error I'm guessing? I think you'll drop a mark

    what i did was used 13.1 and sub into the equation to find y instead of using 13.08...

    is that rounding error?

    According to Arsey 67 should be enough for 90UMS but we can't be sure

    I used 3.1 as well and still got 13.9 (because y=17-x).

    It took me a whole 20 minutes to figure out that I'd need to apply the difference of two squares for that trig question!

    However, I felt that paper challenged me in very similar way to how June 2014 did, so I'd anticipate similar grade boundaries (probably 1/2 marks lower).

    nope one to many. one x value will give you many y values

    oh and the question was asking why it wont be a function

    Hey guys
    So for 8(b) I screwed up and thought it was 2θ so my final answers are divided by two. How many marks would I lose?

    Paper was definitely challenging but doable idk
