6. Suppose that a mapping T from the set P3 of polynomials of degree 3 or less to the set M of 2x2 matrices is defined as follows T(ao + tax + (1ch2 + a3x3) = [a0 a1; a2 a3] Is T one-to-one? Why or why not? Is T onto M? Why or why not? Is T invertible? Why or why not? Is T an isomorphism? Why or why not? PWP!' 7. Suppose that a mapping T from the set P; of polynomials of degree 3 or less to the set M of 2x2 matrices is defined as follows T010 + alx + (12x2 + (13263) = [a0 a1; a2 0] Is T one-to-one? Why or why not? Is T onto M? Why or why not? Is T invertible? Why or why not? Is T an isomorphism? Why or why not? PPP
