Are the following statements true or false? If true give a proof, and if false give a counter-example:
(a)Consider a continuous function f : (0, 1) → R and a Cauchy sequence Xn ∈ (0, 1).Then f(Xn) is also Cauchy.
(b)If Xn <a and limn→∞: Xn =l, then l<a.
(c) For an, bn ∈ R, consider a sequence of open intervals In = (an, bn).
