What is the inverse of the function f(x) = 2x + 1?
charle [14.2K]

Answer:

f^{-1} (x) = \frac{x-1}{2}

Step-by-step explanation:

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

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

\frac{y-1}{2} = x

Change y back into terms of x with x = f^{-1} (x) , so

f^{-1} (x) = \frac{x-1}{2}
