For each of the following LTI systems, find the z-domain transfer function. For these expressions, h[n] is the impulse response, x[n] is the input signal and y[n] is the output signal. Express your answer as either a z polynomial of finite order or as the ratio of two z polynomials of finite order. In all cases, assume that the input signal begins at n=0 or later. Also assume that y[n]=0 for n<0. State whether the system is FIR or IIR.
