    is there a bounds set or do we determine the bounds by the intersecting curves?

    no bounds set

    without set bounds, we should assume that it is the intersection of the two curves

    I set the 2 equal to each other and set it equal to 0

    if we can find the area of half of one of them, we can just multiply by 4 to get the total

    lets use y^2 - 9 since it is a difference of squares: the roots are x=3 and x=-3

    so our bounds to find the area should be between 0 and 3; and we can equate this to x^2 - 9 and be none the worse

    x^2 - 9 integrates up to (x^3/3) -9x at 0 we get a value of zero so thats pointless; use 3

    333 --- - 27 3 9 - 27 = |-18|; one quareter of this is equal to 18 18*4 = 40 + 32 = 72

    question is; am I right? or does everything cancel to zero :)
