writing a reaction on a picture is much more diffecult than on a GeoGebra file itself. So I just give it a try.

Typing the inequality in CAS the result of it is shown as a zone, not as a segment.

In the picture added I see that a segment is shown. I don't know how you drew it, but I suppose it's done based on calculation of the two endpoints. That's the way to do, there's no more direct way if that's your question.

But if you have a more specific question, ask it with the file itself included

What to type in the library box to show a Domain function ?

There's no command to calculate the domain of a function.

If you want to make exercises like in the picture added you could create multiple choice exercises with checkboxes, or just use it as an exercise in a textbook, with the possibility of showing the correct answer using a checkbox.

What's possible with domains is drawing a function with restricted domain with the command:

Function( <Function>, <Start x-Value>, <End x-Value> ), e.g. f(x)=(x², -2, 2)

I don't know if I understand well your question, but it seems I'm not the only one, since you asked it already in another thread and other persons tried to answer it

(https://help.geogebra.org/t...)

Probably it has something to do with the question itself...
