Hi! Please help I am very desperate and I need it solved. Thanks!

F(x)= 1/x-4, g(x)=4x+1/x a. use composition to prove whether or not the functions are inverses of each other. b. express the domain of the compositions using interval notation.

If g(x) is an odd function, which function must be an even function?
