This is not your function, however it illustrates the ‘logical indexing’ approach:
f = @(x) (2-2*x).*(x <= 0) + (2+2*x).*(x>0);
t = linspace(-3, 3);
figure
plot(t, f(t))
grid
ylim([0 max(ylim)])
It is not difficult to figure out how it works. Be inspired by it!

Walter — Thank you!
Dodo — We provide hints for homework assignments, not actual code. If you post the code you have written and are having problems with it, we will help you get it to run. We will not write it for you!
