Hallo,I'm solving an exercise(with matlab)that consist in a discussion of a function in a range. When I watch the graph,I've problem to determine the domain and roots becouse the function is too much near the axis. What command I must use to draw the graph more understandable ??

I have no idea what you're asking, so all I can say is to use the plot() command. Or fiddle around with xlim() and ylim(). Attach some screenshots to illustrate your situation.

在 MATLAB Online 中打开

you can adjust the axis property to zoom in :

 %  x,y
 axis([x(1) x(end) y(1) y(end)])

But for example, please watch the image attached , this is the range: [-5 5]. How you do to understand in a convenient way if the function is on the x axis or just more near??
