Answer 12

Let ƒ be a function defined on an open interval containing c (except possibly at c) and let L be a real number. Then the statement
\[\lim_{x \rightarrow c} f(x)=L\]
means
for all real ε > 0 there exists a real δ > 0 such that for all x with 0 < |x − c | < δ, we have |ƒ(x) − L| < ε

Answer 14

simply they are used as domain and range?

Answer 15

yup! further explanations on them can be found on the wiki page as well. they are just the tiniest difference, because limit is not the equality, but the "approachness", of a function, between the limit and the function.
