If f(x) = 1/9x-2, what is f^-1(x)?

f^-1(x) = 9x + 18
f^-1(x) = 1/9x+ 2
f^-1(x) = 9x+2
f^-1 (x) = -2x + 1 / 3

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
