Problem 2 (8 points) We define the following function between polynomial vector spaces. A: Pd + Pd+1 ad The map A takes in a polynomial and produces a new polynomial with the rule a do +212 + ... + aard H00. + - +...+ -æd+1 d +1 Now, consider another function D:Pa → Pa-1 which is given by the rule 20 + ax +... + adx' + 0 +222 + ... + adxd-1 a. (4 pnts) Are these linear maps? If so, compute their matrices with respect to monomial bases for d= 4. To be specific, that's the basis where (10 (1 p(x) = [1 x ... ad (1) : ad So you would need to compute one matrix A for the function A so that A multiplied by the coefficient vector [az], (d + 1) 1 is the column vector with the output polynomial's coefficients. Then do the same with a matrix D for the function D. b. (4 pnts) Are A and D invertible? If so, what are their inverses? If not, why not?
