Math Problem Statement
For the function f(x) = ³√x + 4, find f⁻¹(x).
Solution
Let's solve the problem step by step. We are asked to find the inverse function for the given function .
Steps to Find the Inverse Function:
-
Express the function: Start with the equation .
-
Swap and : To find the inverse, we switch and :
-
Solve for :
- First, subtract 4 from both sides to isolate the cube root:
- Then, cube both sides to get rid of the cube root:
- So, the inverse function is:
Answer:
The correct inverse function is .
