In each of the following, two open sentences P(x) and Q(x) over a domain S are given. Determine all x ES for which P(x) ⇒ Q(x) is a true statement. (a) P(x) : x 3 = 4; Q(x) : x ≥ 8; S = R. (b) P(x): x² ≥ 1; Q(x) : x ≥ 1; S = R.| (c) P(x): x² ≥ 1; Q(x) : x ≥ 1; S = N. (d) P(x) : x = [1, 2]; Q(x): x² < 2; S = [1,1].
