Answer :
Given function :-
[tex]\bf \implies g(x) = \dfrac{3}{x}+7[/tex]
- To find its reverse , substitute y = g(x) .
[tex]\bf \implies y = \dfrac{3}{x}+7[/tex]
- Interchange x and y .
[tex]\bf \implies x = \dfrac{3}{y}+7[/tex]
- Solve for y .
[tex]\bf\implies \dfrac{3}{y}= x -7 \\\\\bf\implies y =\dfrac{3}{x-7} [/tex]
- Replace y with f-¹(x) .
[tex]\implies\boxed{\red{\bf f^{-1}(x) = \dfrac{3}{x-7} }}[/tex]
