Answer:

Step-by-step explanation:

We want to find the inverse of g(x). One way to do this is to switch the g(x) and x in the original equation and then solve for g(x); that will give you the inverse.

Here, $g(x)=\frac{3}{5} x-9$ . Switch the g(x) and x to become: $x=\frac{3}{5} g(x)-9$ . Now solve for g(x) by isolating it:

$x=\frac{3}{5} g(x)-9$

$x+9=\frac{3}{5} g(x)$

$\frac{5}{3} * (x+9)= g(x)$

$g(x)=\frac{5}{3} x+15$

Thus, the answer is C.

Hope this helps!
