7) Let T : P2 → P2 be defined by T(p(r)) = p(0) + p(1)r. (For example, if p(z) = 3+1+ 4r2, then T(p(t)) = p(0) + p(1)t = (3+0+4 .0²) + (3+ 1+4.12)t = 3+ 8t.) Let a = {1,x – 1,r² – 1} and B = {1,r,r²} be two bases of P2. (a) Find the a-matrix and B-matrix of T. (b) Find the change of basis matrix S3-a. (c) What is the relation of the three matrices you have found? Are any two of them similar? (Recall that similar has a technical meaning %3D here see Definition 3.4.5.)
