(b) Since t2/2 is convex we have t2/2 ≥ x2/2+x(t−x) = xt−x2/2. This is the general inequality g(t) ≥ g(x)+g′(x)(t−x), which holds for any diﬀerentiable convex function, applied to g(t) = t2/2. Another (easier?) way to establish t2/2 ≤ −x2/2+xt is to note that t2/2+x2/2−xt = (1/2)(x−t)2 ≥ 0. Now just move x2/2−xt to the other side.
