D (1) = 0 = 0*x^2 + 0*x + 0*1. The matrix A of a transformation with respect to a basis has its column vectors as the coordinate vectors of such basis vectors. Since B = {x^2, x, 1} is just the standard basis for P2, it is just the scalars that I have noted above. A=. Previously we talked about a transformation as a mapping, something that maps one vector to another. So if a transformation maps vectors from the subset A to the subset B, such that if ‘a’ is a vector in A, the transformation will map it to a vector ‘b’ in B, then we can write that transformation as T: A—> B, or as T (a)=b.
