Question

CAN SOMEONE PLASE HELPPPP ME PLEASE!!!!!!!!!!!!!!!!!!!!!?????????
What is the inverse of the function f(x) = one-ninthx + 2?

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

Answer 1

Given Function,

$f(x) = \frac{x}{9} + 2$

$\frac{1}{f(x)} = \: \frac{1}{ \frac{x}{9} + 2 } = \frac{1}{ \frac{x + 18}{9} }$

$h(x) = \frac{1}{f(x)} = \frac{9}{x + 18}$

This Should Be The Answer .
