This was a bonus question on my test yesterday (I hope I can remember it correctly).
Q: Let W be a subsapce of such that P(0)=0 and let U be a subspace of such that P(1)=0. Find a basis for both W and U.
A: For W I figured the basis ought to be since I don't wan't to have any value. But, I am stuck on U. I think I am seeing it all wrong. My x's are my vectors correct? As in, is my basis for all third degree polynomails which have the form . I tried it a couple different ways on the exam, but should said they were all wrong, but that I was close. Even so, I think I am stuck in a rut and I am having a hard time starting from scratch. Im having trouble finding a systematic approach.
