I have the following matrix
x=[2 3 5 4 6 4];
with index at 5 i-e n=0 at value 5.
n is sampling scale value (-----,3,-2,-1,0,1,2,3----)
I have to plot this signal x(n) on time axis n,
then I have to do the following operations,
x[-n],
x[-n+4]
x[-n-4]
x[n-4]
x[n].u[n-2]
x[n].impulse[n+2]
x[n].impulse[n-2]

to plot discrete signal it is always better to use stem()
and for the first question you can use ,for x[n]
n=-2:3;
stem(n,x);
for x[-n];
n=-n;
stem(n,x);
similarly you can do till x[n-4];
