Question

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

-x + 2?
h(x) = 18x - 2
h(x) = 9x – 18
h(x) = 9x + 18
h(x) = 18x + 2

Answer 1

The answer is h(x) = 9x – 18

Explanation:

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 .
