Let f(x)=1x−5\displaystyle {f{{\left({x}\right)}}}={\frac{{{1}}}{{{x}-{5}}}} and g(x)=2x+5\displaystyle {g{{\left({x}\right)}}}={\frac{{{2}}}{{{x}}}}+{5}.
Then (f∘g)(x)=\displaystyle {\left({f}\circ{g}\right)}{\left({x}\right)}=   ,
(g∘f)(x)=\displaystyle {\left({g}\circ{f}\right)}{\left({x}\right)}=   .
