    thanks

    Perfect, thanks.
    One last thing: do I have to write like this "f o g (x)" when = f(g(x)) or just "f o g" is acceptable?
    I mean: "f(g(x)) = f o g" or "f(g(x)) = f o g (x)" ? or it doesn't matter?

    Re: composite transformation

    Hi This post has helped me with my problem, but I am still confused on the part that says

    if we explicity calculate f(g(x,y)), we get f(g(x,y)) = (y-2, -x).

    so if (x,y) = (y-2,-x) we get 2 equations in x and y. can you solve these?

    How do you find y-2, and -x, I just cant see how you got to these.
    Please help I have nearly no hair left!!
