• Problem 3. Let || . || be any norm on R". Let D CR and let f:D + R". Prove, if f is Lipschitz on D (with respect to the norm || D with Lipschitz constant K >0, then for any subset A CD, that the restriction of f to A, f|A: A + R", defined as f|A(a):= f(a) for a € A, is Lipschitz on A (with respect to the norm || - D with the same Lipschitz constant K.
