Use the MATLAB function stem as follows to draw:

$x[n],x[n-3],x[n+2]$

Try to first delay $x[n+2]$ by $3$ to the right then fold it at the first step

And then at the second step; first: fold $x[n+2],$ then shift to the right by $3$

Then compare these two results plots

stem$($n$,$x$,$'fill'$)$; ylabel$(\text{'}$x$[$n$]\text{'})$; xlabel$(\text{'}$n$\text{'})$;
