Exercise 4.4.9 (Lipschitz Functions). A function f: A → R is called Lipschitz if there exists a bound M > 0 such that f(x) f(y)\ ≤ M x-y for all x + y = A.

Exercise 4.4.9 (Lipschitz Functions). A function f: A → R is called
Lipschitz if there exists a bound M > 0 such that
f(x) f(y)\
≤ M
x-y
for all x + y = A. Geometrically speaking, a function f is Lipschitz if there is a
uniform bound on the magnitude of the slopes of lines drawn through any two
points on the graph of f.
(a) Show that if f: A → R is Lipschitz, then it is uniformly continuous on A.
(b) Is the converse statement true? Are all uniformly continuous functions
necessarily Lipschitz?
