20. Let
(‧) denote the Laplace transform. Which of the followings are true?
(A)
(a₁f₁+a₂f₂) = a₁
(f₁) + a₂
(f₂), for all a₁, a₂ ∈
and for all functions f₁, f₂
(B) if
(f) = F(s), then
= sF(s)
(C) if
(f) = F(s), then
= F(s)/(s+a)
(D) if
(f) = F(s), then
(t² f) =
(E) if
(f) = F(s) and
(g) = G(s), then
(f ‧g) = (F*G)(s), where * denotes convolution operation
