Answer 1

no

Answer 2

why @sourwing

Answer 3

if they are inverse they will always result in x.
if they are not they will be equal but not x.

Answer 4

i dont understand that @humingbird

Answer 5

ok, for example:
f(x)=x+1 h(x)=x-3

f(h(x))= (x-3)+1
=x-2

h(f(x))= (x + 1)-3
=x-2

Answer 6

\[f(x)=2x\]
\[h(x)=x+1\]

\[f(h(x))=2(x+1)=2x+2\]
\[h(f(x))=2x+1\]
