NO In Problems 19-22, we use the usual notation for intervals of real numbers: (a, b) for the open interval {x|a<x<b}, (a, b] for the half-open interval {x|a< x≤ b), [a, b] for the closed interval {x|a ≤ x ≤ b}, [a, co) for the unbounded interval (x/a ≤ x), and so on. The answer to each question should be an interval, a singleton set, or the empty set. 19. Find: (a) [i-1, i) (b) [i-1, i)
