Suppose T: P3R4 is an isomorphism whose action is defined by -2a+d 2b+c Tax3 +bx+cx+d) = -2a+2d c+d Find the inverse transformation T-1 and give its action on a general vector, using x as the variable for the polynomial and p, q, r, and s as constants. Use the " character to indicate an exponent, e.g. px^2-qx+r.
