Please consider to stop using such assignments. It propagates a confusion
between the *function* f and the *expression* f(x). The distinction is
significant in sage and generally brushed over in Calculus, so many users
seem to have problems with it.
Using `fx = function('f')(x)` or `f = function('f')` (and then use `f(x)`
explicitly) may help in driving home the difference (or at least give
examples that people can mindlessly mimic and learn useful habits). It
might even be worth going through the docs and fixing those accordingly.
