An error message indicating that you gave it a “bad initial guess” would be better, but at least the Prime tells you that it found an “Extremum” rather than a root. The 50g actually labels this incorrect point as a “Root”.

Yes; when I was implementing this bit of the UI for the 39gII, I suggested the change in labeling. (To specifically call out that the root finder is returning an extrema.)
