  1. domain: all real numbers except holes and vertical asymptotes

    vertical asymptotes where the denominator is zero and the numerator is not zero

    holes where the denominator and numerator are both zero

    horizontal asymptotes at the x-extremes. When x gets huge, you basically have

    f(x) = x^2/x^2 = 1

    I'm sure you can handle the rest. Get stuck? Come on back and show how far you got.
