2. Determine whether each function is Lipschitz, and if so find its Lipschitz constant.
For all problems, || - || represents the Euclidean norm (2-norm).
(a) f: R" → R for f(x) = ||||
(b) f: R" → R for f(x) = ||*||²|
(c) p: R→ R for p(x) = 1.
1+e
(d) f: R¹ → R for f(x) = p(wªx+b) for some weight vector w € R¹, b € R, and
p from part (c).
