1. Consider the open sentences P(x) : x² < 18. and Q(x) : x ≤ 4. over the domain R. Complete the truth table for Q(x): state all x € R for which Q(x) is true, and all x E R for which Q(x) is false. Complete the truth table for P(x): state all × € R for which P(x) is true, and all x ER for which P(x) is false. Use the tables above to complete the truth table for P(x) ⇒ Q(x).
