-inverse functions <br><br> Find the formula for f^-1(x):<br><br> F(x) = 3x^3 - 5
mamaluj [8]
<h2>Writing the Inverse of a Function</h2><h3>Answer:</h3>

f^{-1}(x) = \sqrt[3]{\frac{x +5}{3}}\\

<h3>Step-by-step explanation:</h3>

<em>Please refer to my Answer from this Questions to know more about Inverse Functions: <u>brainly.com/question/24619467</u></em>

Let y = f(x) so that the inverse of y is equal to f^{-1}(x).

Solving for f^{-1}(x):

f(x) = 3x^3 -5 \\ y = 3x^3 -5 \\ x = 3y^3 -5 \\ 3y^3 -5 = x \\ 3y^3 = x +5 \\ y^3 = \frac{x +5}{3} \\ y = \sqrt[3]{\frac{x +5}{3}}

Since the inverse of y is equal to f^{-1}(x), f^{-1}(x) = \sqrt[3]{\frac{x +5}{3}}\\.
