most 2, and let
Let P₂ denote the vector space of polynomials of degree at
D: P2 → P2
be the transformation that sends a polynomial p(t) = at² + bt + c in P₂ to its derivative
p'(t) = 2at+b, that is,
D(p) = p'.
(a) Prove that D is a linear transformation.
(b) Find a basis for the kernel ker(D) of the linear transformation D and compute its
nullity.
(c) Find a basis for the image im(D) of the linear transformation D and compute its
rank.
(d) Verify that the Rank-Nullity Theorem holds for the linear transformation D.
(e) Find the matrix representation of D in the standard basis (1, t, t²) of P2.
