Question

what is the inverse of the function $f(x) = x^3$?
options:
$3x$
$3 \times$ the square root of $x$
$\frac{x^3}{3}$
the cube root of $x$

Explanation:

Step1: Replace $f(x)$ with $y$

$y = x^3$

Step2: Swap $x$ and $y$

$x = y^3$

Step3: Solve for $y$

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

Answer:

The cube root of x
