Problem 5 The inverse function theorem (12.3) says that, if f : A B is a function, then f is bijective if and only if the inverse relation f-1 is a function from B to A. Explain this theorem and its proof by discussing the key steps in the proof and providing examples illuminating those steps. You should include: several examples of cases in which the theorem tells you that a function has an inverse function, with an explanation. • several examples in which the theorem tells you that a function does not have an inverse, with an explanation. Your examples should include cases in which the sets A and B are both finite and infinite.
