Exercises for January 27:

E 2.2.1, E 2.2.4, and

Exercise 1:

Let X be the vector space C'[0,1] of all continuously differentiable functions on [0,1] with the sup norm. Let Y = C[0,1], also with the sup norm. Define D: X –> Y by (Dx)(t) = x'(t), for all t in [0,1]. Show that D has closed graph but is not bounded. Explain the result in view of the Closed Graph theorem.
