Unformatted text preview: . 3. State the Axiom of Completeness . The Axiom of Completeness is given on page 14 of the text. It says that every nonempty set of real numbers that is bounded above has a least upper bound. 4. Is the statement , ± Every nonempty set of real numbers is bounded above ,² true or false ? If false , explain why . It³s false. The subset N of R is nonempty but is not bounded above....
