How do i graph various conditions in MATLAB

So heres my issue. I have specific conditions. So lets say I want to graph the function y=0.005*x at x<=2000. But. At 2000<x<2500 y=10-0.02*x, and if x>2500, then y=0. I have been doing if and elseif but my graph only shows the first condition. Can you help me with the code?

You can give the code below a try or post your own code so we can help you with your train of thought.

x = 1:4000;
y = zeros(length(x));

for ii = 1:length(x)
    if x(ii)<=2000
        y(ii) = 0.005*x(ii); 
    elseif (2000<x(ii) && x(ii)<2500)
        y(ii) = 10-0.02*x(ii);
    elseif x(ii)>2500
        y(ii) = 0;
    else
        fprintf("Error at %0.f\n",x(ii));
    end
end

plot(x,y)
