    HELP!! Impulse Response h(n) problem

    Please help me solve this problem. Atleast the correct answer indication is also very much appreciated.

    A system has impulse response h(n) = (1/2)^n-3 U(n-3) and the input is x(n) = 3^n U(n)

    a)Find the output by direct convolution.

    b)Find the output by using z-transforms.

    Thanks for your kindness, time and effort.
