Question 2 b
5. The infinity is on the bottom of the fraction. Anything divided by infinity is zero.
6. infinity isn't an actual value itself it describes how big something is

so what it's describing is what happens when x get super super big

well if x is on the bottom of a fraction then we can essentially say that the fraction is 0 because x is so small it's pretty much negligible so we say it's 0

7. So we get

Now what is ??

In other words, what value does approach as tends to infinity?

Side note: it might be tempting for many students encountering infinity in this context to just sub it in, but infinity is not a number so we cannot just sub it in. We need to examine what happens to our function as our variable TENDS TO infinity, which is what I've shown here.
