Question
Let ƒ: S→R  be an uniformly continuous function. Finish the proof, Show limit lim_(x →b)ƒ(x) exists. Show that for ε > 0 there is a δ > 0.
 
Expert Solution
Step 1

Que

Ans : f : (a, b)  to R be uniformly continews function show that  lim(x tend b) f(x)  exist

   Function f is uniformly  continews if for each e>0 there exist d>0 such that

      | f(x) - f(y) |<e whenever |x-y|<d

Chose x, y such that |x-b|<d/2, |y-b|<d/2

 |x-y| <|x-a|+|y-a| <d/2+d/2 =d

So |f(x) - f(y) | <e by definition
