In this problem, the domain of discourse is the set of all integers. Which statements are true? If an existential statement is true, give an example. If a universal statement is false, give a counterexample. (a) 3x (x + x = 1) (b) 3x (x + 2 = 1) (c) Vx (x2 - x + 1) (d) Vx (x2 - x = 0) In this problem, the domain of discourse is the set of all integers. Which statements are true?
