Function Math

Hi there,

Essentially what you're trying to do is break up the given function into two different functions.

In this case, f(x) = 5/x and g(x) = x + 7

Composing those two functions would give you 5/(x + 7).

Problems like this can sometimes have more than one answer (in this case there's only one answer), but generally you just want to look for functions inside of the given function and try to work backwards.
