Question

What is the inverse of f(x) = (x+4)^3

Answer 1

`Answer:\ f^(-1)(x)=\sqrt[3]{x} -4`

Explanation:

`f(x)=(x+4)^3`

Extract the cube root from both parts of the equations:

`\sqrt[3]{f(x)} =x+4\\\sqrt[3]{f(x)}-4=x+4-4\\ \sqrt[3]{f(x)} -4=x`

Redefine the variables:

`f^(-1)(x)=\sqrt[3]{x} -4`
