Hey, I am new to MATLAB and to coding overall, so it should be an easy question answer, but still I am having some trouble. I have to plot agraph that is y=2x from 0 to 3 and y=2.5x from 3 to 4. (The graph I am adding is like what I am trying to plot). The thing is that I can not use commands like piece-wise because I'm using octave for MATLAB language. Thanks in advance.

You can use hold to plot multiple graphs in the same figure. This way you can graph any picewise function:
x1 = 0:3;
x2 = 3:4;
y1 = 2*x1;
y2 = 2.5*x2;
plot(x1, y1);
hold on
plot(x2, y2);
hold off
