Question

Which function is the inverse of ƒ(x) = 4x3 – 2? // its not A

Answer 1

Answer:

C

Step-by-step explanation:

C

Answer 2

Answer:

C) $g(x)=\sqrt[3]{\frac{x+2}{4}}$

Step-by-step explanation:

$f(x)=4x^3-2$

$y=4x^3-2$

$x=4y^3-2$

$x+2=4y^3$

$\frac{x+2}{4}=y^3$

$\sqrt[3]{\frac{x+2}{4}}=y$

$f^{-1}(x)=\sqrt[3]{\frac{x+2}{4}}$

$g(x)=\sqrt[3]{\frac{x+2}{4}}$
