This works because x exists in the function f. Perhaps you want this

Your
want is the opposite. I know the y-value, and I want to calculate the
x-value.

How would I go about officially requesting that this is mentioned, either in
the documentation, or as a warning?

This sounds like a software engineering problem, not an R problem. Does

normally do something like
