Describe the rules for limits at infinity
When the degree of the numerator > degree of denominator: the limit is positive or negative infinity
When the degree of the numerator < degree of denominator: the limit is 0
When the degree of the numerator = degree of denominator: the limit is the coeffiencent of the numerator / the coeffiencent of the denominator
