  1. A system described by a linear, constant coefficient, ordinary, first order differential equation has an exact solution given by y(t) for t > 0 , when the forcing function is x(t) and the initial condition is y(0) . If one wishes to modify the system so that the solution becomes -2y(t) for t > 0 , we need to
  2. A.
    change the initial condition to -y(0) and the forcing function to 2x(t)
    B.
    change the initial condition to 2y(0) and the forcing function to -x(t)
    C.
    change the initial condition to j √2 y(0) and the forcing function to j √2x(t )
    D.
    change the initial condition to -2y(0) and the forcing function to -2x(t)
