Answer:

B.    [tex]f^{-1}(x) = \frac{x + 3}{9}[/tex]

Step-by-step explanation:

[tex]let \space\ y = f(x)\\\\y = 9x -3\\[/tex]

• Now make x the subject of the equation:

[tex]9x = y + 3\\\\x = \frac{y + 3}{9} \\[/tex]

• Replace x with f⁻¹(x) and y with x:

[tex]f^{-1}(x) = \frac{x + 3}{9}[/tex]
