Let Pn denote the vector space of polynomials in the variable x of degree n or less with real coefficients. Let D² : P3 → P1 be the function that sends a
polynomial to its second derivative. That is, D² (p(x)) = p"(x) for all polynomials p(x) E P3. Is D² a linear transformation?
Let p(x) = a3x³ + a2x² + a1x + ao and q(x) = bzx³ + b2x² + b1x + bo be any two polynomials in P3 and c E R.
a. D (p(x) + q(x)) =
- (Enter az as a3, etc.)
