The limit of a function

Let f be a function defined on an open interval containing a, except possibly at a itself.

Then (read as the limit of f(x) as x approaches a is L) if for any >0, there exists a >0

such that |f(x) - L|< whenever |x-a|<

Properties of limits

Given and and L, M, a, c, and n are real numbers, then:
