4. Prove that, if f : A → B has an inverse, then f is bijective. (The converse is also true, and very useful, but you do not need to prove it.) If A is a set, a binary operation on A is a function 3: Ax A→ A. Binary operations are ubiquitous in modern algebra, and their appearance there motivates the following notation: for (a1, a2) € A × A, we write a₁ßa2 instead of the usual functional notation B(a₁, a2) for the image of (a₁, a2) under 3. The most important (and motivating) instances of this (very general) notion for us are the addition and multiplication operations on a ring.

Given any set of 15 integers, must there be two that have the sameremainder when divided by 12? Prove using the pigeonhole principle. Eitherdescribe the pigeons, the pigeonholes, and how the pigeons get to the pigeonholes, or describe a function by giving its domain, co-domain, and how elements of the domain are related to elements of the co-domain.

2. Suppose I wish to define a function g : {0, 1, 2, 3, 4} → Z that takes an input of an equivalence class mod 5 (so one of the numbers 0, 1, 2, 3, or 4), and returns an output of the integer with that equivalence class. Is g a well-defined function? Why or why not?
