Question

If f(x) = 8x, which of the following is the inverse of f(x)?
O A. F'(x) =
-
ID
Х
O B. f-'(x) = x+8
O c. f-'(X) =
8
O D. F-1(x) = x - 8

Answer 1

Step-by-step explanation:

f(x) = y

8x = y

x = y/8

We can note the inverse as

$f^{-1}(y) = \frac{y}{8}$

Or, if you want the function to be expressed as depending on variable x

$f^{-1}(x)=\frac{x}{8}$
