Let V, = xER for each positive integer i. Find each of the following. (Enter your answers using interval notation.) (a) 4 UV, = i = 1 (b) 4 i = 1 (c) Are V, V2, V3... mutually disjoint? Why or why not? O Yes, because no two of the sets V,, V2, V31 ... have any elements in common. O Yes, ecause the union of the sets V,, V2, V3, ... is empty. O Yes, because the intersection of the sets V,, V2, V3 ... is empty. O No, because no two of the sets V,, V2, V31 ... are disjoint. O No, because the sets V,, V2, V3r ... are disjoint. (d) n UV, = i = 1 (e) n i = 1 (f) UV, = 00 i= 1 (g) i = 1
