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.

    I tried to limit the range (r value) on a polar equation inequality, but it wouldn't let me. It said polar equations must be linear in r. I don't see why r can't be limited under these conditions, is this just something Desmos doesn't let you do?

    Is there any way to remove all of my restrictions at once?
