Which of the following statements are true and which are false. justify your answers. hint: this is a great problem. you need to be particularly careful about the order of the quantifiers (β and β).
(a) β β β such that β β β 2 + 2 = 9.
(b) β β β, β β β such that 2 < +1.
(c) β β β€ +, β β β€ + such that = + 1.
(d) β β β€, β β β€ such that = + 1.
(e) β β β such that β β β, = + 1.
(f) β β β +, β β β + such that = 1.
(g) β β β, β β β such that = 1.
(h) β β β€ + and β β β€ +, β β β€ + such that = β
(i) β β β€ and β β β€, β β β€ such that = β
(j) β β β + such that β β β +, <
