Definition 6 2 7 Uniform Continuity A function f with domain D is called uniformly continuous on the domain D if for any 0 there exists a 0 such that if s t D and Proposition 3 The function f x 1 x is not uniformly continuous on the interval 0 1 Proof For a contradiction assume f x is uniformly continuous on 0 1 So for every 0 there
