f(A) is bounded?

I wanna prove this by using the definition of uniformly conti
positively...

I've already know the proof making the compact set(the set of limit
points of A).

Is that last sentence a sentence?

Hint: Let eps = 1, find delta. Pick a point p in A. How far away from
f(p) can f get in a 2 delta size interval from p? How many such
intervals to cover A? So...

I know the rough idea like that, but I can't have the concrete proof.

Sorry for my poor English and math skill ;(- -

Finally I've done it. Thanks.
