Use the definition of uniform continuity to show that any Lipschitz function f on E is uni- formly continuous on E. Hint: Uniform continuity means (Ve) (38) (Vr) (Vy) (x−y| < 8⇒|f(x) = f(y)| < €). Lipschitz means |f(x) = f(y)| < Mx -y, for all x, y in E. Fix € > 0. For which & is it true that f(x) = f(y)| < M x - y < €?

2. Use the definition of uniform continuity to show that any Lipschitz function f on E is uni-
formly continuous on E. Hint: Uniform continuity means
(Ve)(36) (Vx)(Vy)(1* – y| < 8 = |f(x) – f(y)| < e).
Lipschitz means
|f(x) – f(y)| < M |x – y|, for all æ, y in E .
Fix e > 0. For which & is it true that |f(x) – f(y)| < M\x – y| < e?
