11. Let B = [X³, X², X, 1] and C
=
[1, X, X²], which are ordered bases for P3(R) and
P₂ (R), respectively. (Note the orders of these bases!) Define T: P3(R) → P₂ (R) by
T(f) = f'.
(a) Compute c[T]B.
(b) Let f(X) = 4-5X²+2X³. Compute B[f]. Compute T(f).
(c) Define S: P₂ (R) → R² by S(f) = (f(-1), f(1)). Compute D[S]c, where D is the
standard ordered basis of R2. Compute D[ST]3, the matrix of the composition
ST with respect to the bases B and D.
