I still don't see where the two arguments come in in those sentences.
The ones I can translate don't even seem to need any {ka}:

        All grammatical relations relate two arguments.
        ro selbri cu te sumti reda

        Grammatical relations are derived from phrase structure configs.
        lo'e selbri cu se krasi lo jufra stura morna

        This grammatical relation occurs in all languages.
        le selbri cu pagbu ro bangu

If there is no difference, then the concept of "inverse function" is
meaningless.

Functions usually have arguments and values. Given an argument, the
function gives you a value for that argument. At least that is how
things work in basic mathematics, I don't know about linguistics.
