    OK, let's get you started. For the first part, thinking informally at first, what bits of the expression dominate the others as x \rightarrow \infty ? It's the x^2 terms isn't it? So what do you think the limit will be? To make this formal, divide top and bottom of the expression by x^2 and think about what happens as x \rightarrow \infty

    The second part assumes the answer to the first part is that both limits are finite. If that is true, are there are any finite values of x where that function is going to blow up to infinity? How might that happen?
