Question

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

Answer 1

`f^(-1)`(x) = x - 1

Explanation:

Let y = f(x), that is

y = x + 1

Rearrange making x the subject

Subtract 1 from both sides

y - 1 = x ( change y back into terms of x for inverse )

x = y - 1, hence

`f^(-1)`(x) = x - 1

Answer 2

`f(x)=x+1\implies\boxed{f^(-1)(x)=(1)/(x+1)}`
