So here I have this crazy function, 9x to the 7th minus 17x to the 6th plus 15 square roots of x, all of that over 3x to the 7th plus 1,000x to the 5th minus log base 2 of x. So what's going to happen as x approaches infinity? And the key here, like we've seen in other examples, is just to realize which terms will dominate. So for example, in the numerator, out of these three terms, the 9x to the 7th is going to grow much faster than any of these other terms. So this is the dominating term in the numerator. And the denominator, 3x to the 7th, is going to grow much faster than an x to the 5th term, definitely much faster than a log base 2 term. So at infinity, as we get closer and closer to infinity, this function is going to be roughly equal to 9x to the 7th over 3x to the 7th.
