Notes:
If the degree of the numerator is greater than the degree of the denominator, then when x is approach infinity, y is also approaching infinity.
If the degree of the numerator is equal to the degree of the denominator, then when x is approach infinity, y is approaching the coeffienct of p(x)/q(x)
If the degree of the numerator is less than the degree of the denominator, then when x is approah infinity, y is approaching zero.
Let's look at an example:
As , the ratio goes to zero and also goes to zero.
As ,
As
