Question

What is the inverse of the function f(x)=1/9x+2

Answer 1

Add x x and 0 0 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=9x−18 f - 1 ( x ) = 9 x - 18 is the inverse of f(x)=19x+2 f ( x ) = 1 9 x + 2

Explanation:

Answer 2

f ^− 1 ( x ) = 9 x − 18

Explanation:

To find the inverse, interchange the variables and solve for y .
