Homework Statement
Show that B = {x2 −1,2x2 +x−3,3x2 +x} is a basis for P2(R). Show that the differentiation map D : P2(R) → P2(R) is a linear transformation. Finally, find the following matrix representations of D: DSt←St, DSt←B and DB←B.

The Attempt at a Solution
I have proved that it is a linear transformation, but I'm really not sure where to begin with the second part. Any help would be appreciated. Thanks
