(4) (14 Points) Consider the function f:R → R given by 1, X EZ f(x) = 0, 2€ Z. 2}={I = = E (a) Does lim,+ f(x) = f()? Prove your answer (using the e- N definition of a limit). (b) Does limx40 f(x) = f(0)? Prove your answer (using the € – N definition of a limit). (c) Is f continuous on R? Justify your answer.
