Document Summary
Prof. s. hudson: [20 pts] answer true or false. In are intervals in the real line; use this in the rst ve. n=1in, where. If the in are open then a is open. If the in are bounded then a is bounded. If the in are open and nested (in+1 in), then a contains a rational number. If the in are closed then a is nonempty. If a contains 3 and 5, then a contains 4. Every non-empty subset of the extended real number system has a least upper bound. The set of all polynomials (of arbitrary degree) with integer coe cients is countable. Every in nite subset of the interval [0, 2 ] has a limit point. The set of positive rational numbers is dense in the real numbers. Any set s r with at least one interior point has at least 10 interior points: [15 pts] let a = {(x, 0) r2 : x r1} (the x-axis).
