You can generalize seperateFuncs to Applicative (or Monad) pretty cleanly: seperateFuncs :: (Applicative f) => f (a -> b) -> (a -> f b) seperateFuncs f x = f <*> pure x. Written in point-free style, you have seperateFuncs = ( (. pure) . (<*>)), so you basically want unap . (. extract), giving the following definition if ...

First of all f is supposed to be defined on A, but the domain of f seems to be { 1, 3, 4 } ≠ A, and the range of f which should be a subset of B is { 4, 5 }. Moreover, f ( 3) is both 4 and 5.
