How to find domain of a function in HP Prime?

[mobra66]

Sorry, but this is only more references for how to use and how to specify the domain, which I already know.

No examples of how to calculate/derive the domain of a function (in CAS).

I am getting convinced that this is not currently a feature in the HP Prime.

@make: I think, you don't understand what he is looking for! He is looking for a command, whitch gives the valid domain as a result of a function like:

validdomain('x/(x-1)') results in x<>1 (<> means not  equal)

The name of the command is no real command for the prime but to show what is wanted. Such a command I've not found in the manual.

In your link DOMAIN and CODOMAIN are only used to explain how a function works and not as commands or built-in functions
