I don't think so. It doesn't exist for the same reason the function to
give an interval where a function is continuous doesn't exist: because
it's a lot harder to actually implement than it sounds (plus the one
would depend on the other).
I think a good start would be to implement some way to represent it
symbolically. Maybe we should extend Max and Min to work with any kind
of set and use ImageSet. Or maybe it would be cleaner to represent it
with something like Max(f(x), Interval(0, 1)) (mathematically, max
with the subscript).
This actually relates to several functions. We need a uniform way of
representing things like OP_{x \in SET} f(x), to use a pseudo-latex
notation. ImageSet can work, but it forces you to rethink of it as OP
NEWSET, where NEWSET is {f(x) | x \in set}, in other words, OP becomes
a set function rather than a normal function applied over a set of
inputs.
