1) There is a continuous function from [1, 4] to R that is not uniformly continuous. True or False and justify your answer.
2) Suppose f : D : →R be a function that satisfies the following condition: There exists a real number C ≥ 0 such that |f(u) − f(v)| ≤ C|u − v| for all u, v ∈ D. Prove that f is uniformly continuous on D
Definition of uniformly continuous: A function f: D→R is called uniformly continuous iff for all sequences {an} and {bn} in D if (an) - (bn)→ 0 then f(an) - f(bn)→ 0
