EXERCISE 1.3.1: Unions and intersections of sets Define the sets A, B, C, and D as follows: A-(3,0, 1,4, 17) B (-12-5, 1,4,6) C={x Z: x is odd) D = {xe Z: x is positive) For each of the following set expressions, if the corresponding set is finite, express the set using roster notation. Otherwise, indicate that the set is infinite. (a) AuD (b) An B (c) AnC (d) Au (BnC) (e) AnBn C () AuC (g) (AuB)nC
