Derive the closed-form expression for the complete response (by finding the zero-state response using the convolution-summation and the zero-input response) of the system governed by the difference equation
with the initial condition y(-1) = 1 and the input x(n) = nu(n). List the values of the complete response y(n) at n = 0, 1, 2, 3, 4, 5. Deduce the expressions for the transient and steady-state responses of the system.
