What is the inverse function of f(x) = 19/x^3
2 answers:
Answer:
Step-by-step explanation:
1) Replace f(x) with y: y = 19/x^3
2) Interchange x and y: x = 19/y^3
3) Solve this result for y: xy^3 = 19, or y^3 = 19/x, or
y = ∛[19/x]
-1
4. Replace this y with the label f (x) = ∛[19/x]
Answer:
The inverse function of 
![f(x)^{-1}=\sqrt[3]{\frac{19}{x}}](https://tex.z-dn.net/?f=f%28x%29%5E%7B-1%7D%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B19%7D%7Bx%7D%7D)
Step-by-step explanation:

Steps to inverse the functions:
Step 1: x ⇔ y

Step 2 : now solve the equation for y:

![y=\sqrt[3]{\frac{19}{x}}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B19%7D%7Bx%7D%7D)
The above equation is the inverse of the given function f(x).
![f(x)^{-1}=\sqrt[3]{\frac{19}{x}}](https://tex.z-dn.net/?f=f%28x%29%5E%7B-1%7D%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B19%7D%7Bx%7D%7D)
