1a. Show that for the closed interval [a, 6], its set of interior points is the open interval (a, b) and its boundary points are the endpoints {a, b}. b. Differentiate the intervals (a, b), [a, b], and [a, b) in terms of their boundary points. In terms of its interior and boundary points, what can you say about the set of reals R?
