2. Gradient Descent and Line Search. For the function f (ax) given in the previous problem above, implement gradient descent and plot the suboptimality vs iteration for: (a) gradient descent implemented using a xed step size computed as suggested in the lectures (i.e., as function of the smoothness parameter you computed above), and (b) gradient descent using line search7 as explained in the lectures
