    Heres the answers for the previous steps I got.

    A - y = 2 - 3/(X+2)

    B - Sketchd graph - asmptotes at X = -2 and Y = 2 [Dont think this is needed for part D]


    C - i - ln 3
    - ii - 1/3



    D - Ive got about 1/2 way.
    My last step is


    Integral of Pi Y^2 =

    Pi [4x] between 4 and 0 - 12(ln3) + 9 (1/3)

    It's mathtype. I was thinking of learning Tex but mathtype looks almost as good and is extremely easy to use, so i'll probably put off learning Tex until later when I need it in my degree.
    I downloaded it yesterday so i'm using it a little, because it looks better and so I can become more profficient with it.
