SOLUTION: composition of functions Given: f(x)= 2/x (fof)(x) so far i have (fof)(x)=f(f(2/x))=f(2/x)=2/2/x however i need to slipify this farther and do not know how.

Question 339989: composition of functions
Given: f(x)= 2/x
(fof)(x)
so far i have
(fof)(x)=f(f(2/x))=f(2/x)=2/2/x
however i need to slipify this farther and do not know how.
