Question

F(x)=3x 3 inverse function

Answer 1

Step-by-step explanation:

if I understand this correctly than you are looking for the inverse function of f(x) = y = 3x³.

the inverse function simply tries to calculate the original x it of the original y.

and then, to make it a formal function, we rename x to y and y to x.

y = 3x³

x³ = y/3

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

=> as "regular" function

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