Definition: Uniformly Continuous Functions (Real Case)

Let \(D\subset\mathbb R\) be a subset of real numbers $\mathbb R$ and let $f:D\mapsto \mathbb R$ be a function $f$ is called uniformly continuous, if and only if for every $\epsilon > 0$ there is a $\delta > 0$ such that $$|f(x)-f(y)| < \epsilon$$ for all $x,y\in D$ with $$|x-y| < \delta.$$
