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:

    h(x)=9x-18

    Explanation:

    1. Given  

                    f(x)=\dfrac{1}{9}x+2

    2.  Replace the name of the function with the variable

                     y=\dfrac{1}{9}x+2

    3. Swift x and y

                   x=\dfrac{1}{9}y+2

    4. Solve for y

                    x-2=\dfrac{1}{9}y

                    9(x-2)=y

                     9x-18=y

                     y=9x-18

    5. Name the function

                       h(x)=9x-18\leftarrow answer
