(1 point) Let P be the vector space of all polynomials (of all degrees) with real coefficients. In this problem, we will consider the linear functions d: P + P and s: P +P defined by d(p(x)) = P(x), s(P(x)) = xp(x). In words, d is the function that takes the derivative of a polynomial, and s is the function that multiplies a polynomial by . (a) Let p(x) = -2.0° – 2.02 – 3+1 and...
