I didn't downvote but I'd be interested to know what the domain is here -- I'm not going to play dumb and be like, 'rocks are not functions', but I'm not sure exactly what class of thing you're asking for examples of.
I think it's just that you can make alternative (to set theory) formalizations of mathematics in terms of functions and in consequence anything that is thinkable of in terms of mathematics (which includes all computation).
