y = 9 - x
Put x for y and y for x. Then solve for y
x = 9 - y
y = 9 - x
Final answer. The inverse is itself.

Function?

the inverse means finding f(-x)
so, it becomes:
9 - (-x) = 9 + x

f(x) = 9 - x = y
solve for x , we have : x = 9 - y
we can see that with a certain value of y, we can only have one value of y
so we conclude that y = g(x) = 9 - x is the inverse of itself ( because f(x) = g(x) = 9 - x )

f(x) = 9-x
y = 9-x
x = 9-y
-y=x-9
y = -x+9
f(x) = -x+9
