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

Answer:

h(x) = 9x – 18

Step-by-step explanation:

f ( x ) = 1 9 x+ 2 → Switch the  

f ( x ) with a  y

y = 1 /9 x + 2 →  Switch the places of the x and the y variables

x= 1/9 y + 2 →  Solve for y

x − 2 = 1 /9 y  

y = 9 x − 18
