2. (lUpp.) Let U:={f 6 PAIR) : f(1) = 0} and W:={f 6 733GB) : f'(1) = 0}. Choose a basis for U D W and extend it in two ways: to a basis of U and to a basis of W. Is the resulting list of all vectors (the basis for U ['1 W and all the vectors you added for the two extensions) 3 basis for 733(3)? Explain your answer. (Note: you are not required to prove that U and W are subspaces of P3(]R); they are.)
