how can i plot func between the interval below , i don't have an image of the function anymore but the exact way the function was given was sin(3*x^2) , i'm not receiving any errors just a blank figure
x=-23:.1:23;
func=sin(3*x.^2);
plot(x,func);grid on;axis tight;

The code you posted worked fine for me. Is there some additional code you have with this? Perhaps the issues lies there.

ok so i did it without the subplot and it works ,but the figure is supposed to be there in the top left corner , it's a requirement , i tweaked it's position to (2,2,2/3/4) and still no display , how can i make it function ?

ok so i moved the subplot 2 lines up and put it before the plot and got it to work
x=-23:.1:23;
func=sin(3*x.^2);
subplot(2,2,1);
plot(x,func);grid on;axis tight;
title('func=sin(3*x^2)');
