SUMMARY
If a function f: (0,1) → ℝ is uniformly continuous, then it is necessarily bounded. This conclusion stems from the properties of uniform continuity, which ensures that for every ε > 0, there exists a δ > 0 such that for all x, y in (0,1), if |x - y| < δ, then |f(x) - f(y)| < ε. The Weierstrass Theorem can be applied to reinforce this argument, as it states that a continuous function on a closed interval is bounded. Thus, uniform continuity implies boundedness in this context.
