Matlab Causal system Problem

For the causal system described by the equations with differences:

𝑦 (𝑛) = 𝑥 (𝑛 - 1) - 2.2𝑥 (𝑛 - 2) + 𝑥 (𝑛 - 3) - 17 𝑦 (𝑛 - 1) + 3.123𝑦 (𝑛 - 2)

If the input is: 𝑥 (𝑛) = (0.9) 𝑛 [u (n) -u (n-8)]

Account:

a) Impulsive response h (n).

b) Convolution y (n) = x (n) * h (n).

c) The transformation of z to h (n), ie H (z).

d) Poles and zeros and construct them graphically.

e) ZEK convergence zone.

How can i solve this?. I am really confused.

This sounds like a homework assignment. If it is, show us the code you've written to try to solve the problem and ask a specific question about where you're having difficulty and we may be able to provide some guidance.

If you aren't sure where to start because you're not familiar with how to write MATLAB code, I suggest you start with the MATLAB Onramp tutorial (https://www.mathworks.com/support/learn-with-matlab-tutorials.html) to quickly learn the essentials of MATLAB.

If you aren't sure where to start because you're not familiar with the mathematics you'll need to solve the problem, I recommend asking your professor and/or teaching assistant for help.

Help me in this Question

To check system casuality ?

clc

clear

close all

t=-5:0.01:5;

y=x*x(t)+t*x(t+3);

Now how i check
