Question

What is the inverse of this function?
f(1)
3
r + 12

Answer 1

Answer:

C

Step-by-step explanation:

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

y = $\sqrt[3]{x+12}$ ( cube both sides )

y³ = x + 12 ( subtract 12 from both sides )

y³ - 12 = x

change y back into terms of x with x = $f^{-1}$ (x) , then

$f^{-1}$ (x) = x³ - 12
