Hello everyone, this is my first topic on this forum, so if by chance this question was asked in the past, redirect me to the relevant post.
So, I understand the definition of function limit, I just can't figure how to solve those problems.
For example, I have
So I write |x²-9|<ε, 0<|x-2|<δ
and what's now? I know that probably I should assume that δ<1 or something, and then I stuck.
If there a place when I can see just a big amount of examples, this would be great.
