Question

find the inverse of f(x)=(x-1)/(x+1)

Answer 1

Step-by-step explanation:

We have,

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

Let

$y = f^{ - 1} (x)$

Putting

$f(x) = x \: \: and \: \: x = y$

in the given function

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

$= > xy + x = y - 1$

$= > x + 1 = y(1 - x)$

$= > y = \frac{1 + x}{1 - x}$

Hence inverse of f(x) is (1 + x)/(1 - x)
