Problem 2.
(a) let p(z) be a statement whose truth value depends on z. an ezample is a value of z that makes p(x) true, and a counterezample is a value of x that makes p(x) false. fill in the blank spaces with "is true", "is false'", or "nothing" as appropriate: "3z s. t. p(x)" an example proves a counterexample proves
in (b) - (h), determine whether the given statement is true or false, and briefly justify your answer.
