Question

I need the answer to the image attached

Answer 1

Answer:

D

Step-by-step explanation:

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

y = $\frac{8}{x}$ ( multiply both sides by x )

xy = 8 ( divide both sides by y )

x = $\frac{8}{y}$

Change y back into terms of x

$f^{-1}$ (x) = $\frac{8}{x}$ ← with restriction x ≠ 0 → D
