Usual range-finding methods. For this one, I thought that if the exponent of the numerator is smaller than that of the denominator, then there should be an asymptote at y=0, aka the range doesn't include 0. I think there is a special case for when the exponent on the numerator is exactly one greater than that of the denominator, but I'm not completely sure...
The Attempt at a Solution
Already explained my reasoning. But, range should be y[tex]\neq[/tex]0.
