Select the correct answer. Which function is the inverse of ?

Artyom0805 [142]

Answer:

B. $f^{-1}(x) = \frac{x + 3}{9}$

Step-by-step explanation:

$let \space\ y = f(x)\\\\y = 9x -3\\$

• Now make x the subject of the equation:

$9x = y + 3\\\\x = \frac{y + 3}{9} \\$

• Replace x with f⁻¹(x) and y with x:

$f^{-1}(x) = \frac{x + 3}{9}$
