2. Let f be a function. Let a, M E R. Assume that f is defined on some open interval around a, except maybe at a. Prove the following two statement are equivalent. We have discussed this in our lecture. Now let's write the formal proof. (1) For every MER, there exists 8 > 0 such that 0 M. (2) For every ME Z, there exists 8 > 0 such that 0 M
