| Aug 27, 2015 at 7:27 | comment | added | yohbs | @J.M. I wonder whether I should accept one of the answers or not. There's really no "correct answer" here, and this kind of a community wiki question. | |

@Peltio, yeah I remember that… now I'm wondering which of RootSearch[] or Wagon's FindAllCrossings[] came first.

The answer depends on how f is represented. Is it a pure black box, or is it possible to do exact operations on it (to, as a random example, factor out found roots). Can we take its derivatives? Can we assume it is defined outside of Interval[{x1,x2}], perhaps out onto some open set of the Complexes?
