Let f : (0, 1) R be a function and let a (0, 1). Match each statement in Group A with a statement from Group B which means the same thing. Group A: (i) > 0, > 0 such that |x a| < implies |f(x) f(a)| < . (ii) > 0, > 0, |x a| < implies |f(x) f(a)| < . (iii) > 0 such that > 0, |x a| < implies |f(x) f(a)| < . (iv) > 0 and > 0 such that |x a| < implies |f(x) f(a)| < . (v) > 0, > 0 such that |x a| < implies |f(x) f(a)| < . (vi) > 0 such that > 0, |x a| < implies |f(x) f(a)| < . Group B: (a) f is continuous at a. (b) f is bounded on (0, 1). (c) f is constant on (0, 1) (d) There is some neighbourhood of a on which f is bounded. (e) There is some neighbourhood of a on which f is constant
