How would you tackle this question? [Area]

I'm not asking you to do it for me (unless you want to(Wink) ), but i just dont know what to do, so what would you do..?

Heres the Q:

For the function http://thestudentroom.co.uk/latexren...e9f3f6cc14.png, the ratio of area A:Area B is *n:1*, where A is the area from y = 0 to 1 and the y axis, and B is the area from x = 0 to 1 and the x axis. As shown:

Is this ratio true for the general case http://thestudentroom.co.uk/latexren...e9f3f6cc14.png from x = a to b such that a < b, and for the regions defined below?

Area A: http://thestudentroom.co.uk/latexren...e9f3f6cc14.png, http://thestudentroom.co.uk/latexren...8891219205.png, http://thestudentroom.co.uk/latexren...e82284722e.png and the y axis

Area B: http://thestudentroom.co.uk/latexren...e9f3f6cc14.png, http://thestudentroom.co.uk/latexren...deb8e35f9a.png, http://thestudentroom.co.uk/latexren...16a6df9829.png and the x axis

If so prove it; if not why not?

Once again, I'm not asking you to do it for me, I just need help as to what to do

I've proven that the ratio holds for like x = 0 to 5, or 2 to 7, but what else do i need to do?/ What is the question really asking for
