Question 18 Suppose f: (0, 1)→ R is continuous and let (an) be a Cauchy sequence in (0, 1). Consider the following statements: (i) f((0, 1)) is open. (ii) (f (an)) is a Cauchy sequence. Which statements must be true? O Both statements must be true. O Statement (ii), but not statement (i), must be true. ONeither statement must be true. O Statement (i), but not statement (ii), must be true.
