Answer:


\boxed{\sf g^(-1)(x) = (5)/(4)(x - 3) }

Explanation:


\sf g(x) = (4)/(5)x + 3

The inverse of the function is the function that reverses the input and output of g(x).

In other words, if y = g(x), then the inverse function, denoted by
g^(-1)(x) , gives us
\sf x = g^(-1)(y)

To find the inverse of g(x), we can swap the variables x and y and solve the resulting equation for y.


y = (4)/(5)x + 3

Swap the value;


\sf x = (4)/(5)y + 3


\sf x - 3 = (4)/(5)y


\sf (5)/(4)(x - 3) = y

Therefore, the inverse of the function is the function:


\boxed{\sf g^(-1)(x) = (5)/(4)(x - 3) }
