Mathematics

Answer:

B

Step-by-step explanation:

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

y = (2x - 4)² ( take the square root of both sides )

\sqrt{y} = 2x - 4 ( add 4 to both sides )

\sqrt{y} + 4 = 2x ( divide terms on both sides by 2 )

\frac{1}{2}\sqrt{y} + 2 = x

x = \frac{1}{2}\sqrt{y} + 2

Change y back into terms of x

f^{-1}(x) = \frac{1}{2}\sqrt{x} + 2, x ≥ 0
