If F(x) = x - 1, which of the following is the inverse of F(x)?
O A. F'(x) = x + 1
O B. F1(x) = x
O c. Fl(x) = 1 - x
O D. F1(x) = x - 1

Respuesta :

Answer:

A

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = x - 1 ( add 1 to both sides )

y + 1 = x

change y back into terms of x, hence

[tex]f^{-1}[/tex] (x ) = x + 1 → A
