Answer:

f⁻¹(x) = 9(x+2)

Step-by-step explanation:

Given the function

f(x) = 1/9 x - 2

We are to find the inverse of the function

Let y = f(x)

y = 1/9 x - 2

Replace y with x

x = 1/9 y - 2

Make y the subject of the formula

1/9 y = x + 2

Multiply through by 9

y = 9(x+2)

Hence the inverse of the function is 9(x+2)
