x=linspace(0,10,100);
y1 = 5*x.^2 + 9*x - 5;
y2 = -2*x.^2 + 4*x + 10;
plot(x,y1,'r'); hold on;
plot(x,y2,'b');
legend('y1','y2')

Hi Mohsen, it's very generous of you to answer this kinds of questions but please be aware that you might be doing the homework of others, they should at least show some effort solving their assignments not just copying and pasting the questions, they learn nothing, thanks
