The universal set in these problems is U = {−10, −9, −8, . . . 18, 19, 20}. Note that this set is not symmetric around 0. Define the following sets in universe: A = {−9, −7, −3, −2, 1, 7, 8, 16, 20} B = {x ∈ U : x ≤ 5} C = {x ∈ U : x is even} D = {x ∈ U : |x| ≥ 8} Give two non-empty proper subsets of C.
