I do not know what the code problem is for not plotting:
x=-100:0.001:100;
y=3x+1./(x+2)*(x-3);
plot(x, y, 'k-', 'LineWidth', 2);
grid on;
xlabel('X', 'FontSize', 20);
ylabel('Y', 'FontSize', 20);

You can't use 3x in MATLAB ... you have to use 3*x. And you need to use the element-wise .* operator instead of the matrix multiply * operator.
y = 3*x+1./(x+2).*(x-3);
And, if you meant for all of the (x+2)*(x-3) stuff to be in the denominator, then you would need to use parentheses:
y = 3*x+1./((x+2).*(x-3));
