Now let's think about this one. What is the limit of this crazy function as x approaches infinity? Well, once again, what are the dominating terms? In the numerator, it's 4x to the 4th. In the denominator, it's 250x to the 3rd. These are the highest degree terms. So this is going to be the same thing as the limit as x approaches infinity of 4x to the 4th over 250x to the 3rd, which is going to be the same thing as the limit of 4.
