Calculus

The end behavior of f(x)=(2+x^2)/(x^2-36) most closely matches which of the following:
y=1
y=-1
y=2
y=0
There is no leading coefficient so I am not sure what the answer is.

  4. as x gets huge, the 2 and the 36 become insignificant:

    y -> x^2/x^2

  6. since when is x^2/x^2 = 2?

    10/10 = 1
    z^3/z^3 = 1

    don't forget your Algebra I now that you're taking calculus.

    Using the usual method, divide top and bottom by x^2. That gives you

    (1 + 2/x^2)/(1 - 36/x^2)

    as x^2 gets huge, 1/x^2 -> 0
    and the fraction becomes 1/1

    NOT 2!!
