Consider the function x is rational, x # 0 f (x ) = 3-x2 x is irrational undefined x = 0 Which of the following is correct. Justify your reasoning. a) There is no a for which lim f (x) exists x- a b) There maybe some a for which lim f(x) exists, but it is impossible to say without more x - a information lim f(x) exists only when a = 0 lim f(x) exists for infinitely many a x - a
