1. The problem statement, all variables and given/known data Determine which of the following statements are true. Give proofs for the true statements and counterexamples for the false statements. 2. Relevant equations B. Every non-decreasing function from R to R is injective. 3. The attempt at a solution So I think I know a function that would suit, but I can't just give a drawing of a graph as a proof. I think it would be a function that would be increasing, eventually go monotone for a little while, and then continue to increase to infinity. Does anybody know a function that would represent this well?
