Find the truth set of each predicate. a. predicate: 6/d is an integer, domain: z b. predicate: 6/d is an integer, domain: zt c. predicate: | < x" < 4, domain: r d. predicate: 1 < x
a. Truth set: {6, -6, 3, -3, 2, -2, 1, -1}
b. Truth set: {3, -3, 2, -2, 1, -1}
c. Truth set: (no valid truth set as the predicate is incomplete and contains errors)
d. Truth set: {2, 3}
