Domain and Range Restrictions

To limit the domain or range (x or y values of a graph), you can add the restriction to the end of your equation in curly brackets {}. For example, y=2x{1<x<3} would graph the line y=2x for x values between 1 and 3.

 

You can also use restrictions on the range of a function and any defined parameter.

 

 
 
It's also possible to add multiple restrictions to the same expression line regardless of what parameter is being restricted.

    Is it possible to restrict multiple segments of an equation so you can leave more than one piece of it? If not, I think it would be very efficient and a great feature to add to desmos. Thanks!

    hi I have the line -300x\sin M+y\cos M\ =\left(\ x\cos M+y\sin M-N\right)^2+V\ \left\{y\le810.00\right\}, that i have restricted y of but I also want to restrict x, however, my line gets deleted every time I try to restrict x as well. How do i restrict it so that it works?
