How can I set a domain of all the real numbers except a particular number in Geogebra?
Answered
So I want to find the inverse of e(x) = x / (x + 2). This function has all the real numbers except 2, where is undefined. What I tried to do was to do an ifstatement saying (if x != 2, x / (x +2)), but it stills give me undefined. Is there a way to plug the domain of this function? Without this value it should have indeed an inverse.

OK, try this
orI also didn't notice that this function is restricted on 1, as the inverse would be undefined. So, it would be cool to know about a way to have the domain as all the real numbers except these last two.
There are restrictions on the use of Invert( ) command for functions.
Please see the wiki. https://wiki.geogebra.org/e...
