18.Consider the following differential equation for the function y(t) defined for t ≥ 0

where u(t) is the usual unit-step (Heaviside) function and where * is the usual convolutional
operation of two functions. Assume y(t) = 0 for t < 0. Given the initial condition
y(0) = 1, which of the following staterents is/are true regarding the Laplace transform
Y(s) = ((t)] of solution y(t) in the above equation?
(A) Y(s= )= -6
(B) Y(s=1)=1
(C) Y(s=2)=
(D) Y(s=3)=

(E) None of the above is true.
