Please answer True or False for the following statements... 1. For every nonnegative integer n, 9|(64^n - 1) (believe this is True but don't know how to check or make sure) 2.Let A = B be a finite set of real numbers. If f:A->B is 1-1 then f is onto (I think this is true but what's the definition that cooroborates this?) 3. Let A = B be a infinite set of real numbers. If f:A->B is 1-1 then f is onto (no idea for infinite sets)

There is a reason all our definitions in this class begin with ∀ > 0. Here are two results which can be considered two sides of the same concept – I consider it the fundamental observation of analysis – which is the reason for this ubiquity of ∀ > 0. a) Let c be a nonnegative number, i.e. c ≥ 0. Suppose c ≤ for all > 0. Prove that c = 0.
