HELP :)
find the function and their domain
f(x)= x+(1/x), g(x)=x+14/x+2

(fog)(x)=
(gof)(x)=
(fof)(x)=
(gog)(x)=

Answer 1

The first one means replace eqch x in the function f with x + 14/(x+2)

Answer 2

The second one means replace each x in the function g with x+(1/x)

Answer 3

The third one means replace each x in the function x with x+(1/x)

Answer 4

Sorry. The third one means replace each x in the function f with x +(1/x)

Answer 5

The fourth one means replace each x in the function g with x+14/(x+2)
