Answer :
Converting an equation into inverse function, we need to interchange x with the y.
f(x) = 1/9x + 2
y = 1/9x + 2
Interchange x and y
x = 1/9y + 2
Get the y.
-1/9y = -x + 2
1/9y = x - 2
y = 1/9x - 2/9
So the final answer is
y = 1/9x - 2/9
f(x) = 1/9x + 2
y = 1/9x + 2
Interchange x and y
x = 1/9y + 2
Get the y.
-1/9y = -x + 2
1/9y = x - 2
y = 1/9x - 2/9
So the final answer is
y = 1/9x - 2/9
