Well, it's just going to keep growing forever. So this right over here is just going to be infinity. Infinity times some number right over here is going to be infinity. So the limit as x approaches infinity of all of this, it's actually unbounded. It's infinity. And a kind of obvious way of seeing that right from the get-go is to realize that the numerator has a 4th degree term, while the highest degree term in the denominator is only a 3rd degree term. So the numerator is going to grow far faster than the denominator.
