Consider this very simple example of limits(adsbygoogle = window.adsbygoogle || []).push({});

limit_{x->2 (}x^{2}-4)/x-2

value of function at x=2 is not defined. but rearranging function like this limit_{x->2}x+2 gives us it's limit at x=2.

My question is how rearranging a function gives limit of that function at the specified point..

I have studied limits fully (as much as it is in my course book) don't go to question heading.

thanks for answering.
