Statement for two functions

Suppose f and g are odd functions so that the composite fg makes sense. Then, fg is also an odd function.

Note that composition of functions does not commute, so if we can make sense of both fg and gf, these are both (possibly equal, possibly distinct) odd functions.

Statement for more than two functions
