Question

What is the inverse of the function f(x)=8x+1

Answer 1

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

Step-by-step explanation:

Given:

$f(x) = 8x +1$

First step: Let f(x) be y, the function then becomes

$y = 8x + 1$

Step 2: Make x the subject of the formula: That is

$8x = y + 1$

$x = \frac{y-1}{8}$

Step 3: Replace x with $f^{-1}(x)$  and y with x.

Therefore:

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

Answer 2

The inverse of the function f(x)=8x+1 is;

• f-¹(x) = (x - 1)/8

The function can be written as y = 8x + 1 for evaluation.

By making x the subject of the function; we have;

• x = (y - 1)/8

By swapping x and y; we have;

• y = (x - 1)/8

Ultimately, the inverse of the function is; f-¹(x)=8x+1
