Substitute x = 2 and use the squeeze theorem.

Hm this requires an advanced knowledge. I got it. Let me read squeeze theorem in the book first and try. Thanks for pointing out what topic and how. This is really helpful. I will read and try.

The squeeze theorem isn't all that "deep". If f(x) lies between a(x) and b(x) and a(x) and b(x) both go to 2, what do you think has to happen to f(x)? Do you see where the "squeeze" is?
