Math Problem Statement

Find the inverse function of f(x)=10+x3. f-1(x)= 

Solution

To find the inverse of the function f(x)=10+x3f(x) = 10 + x^3, follow these steps:

  1. Start by rewriting the function: y=10+x3y = 10 + x^3 where f(x)=yf(x) = y.

  2. Swap xx and yy to find the inverse: x=10+y3x = 10 + y^3

  3. Solve for yy: x10=y3x - 10 = y^3 y=x103y = \sqrt[3]{x - 10}

So, the inverse function is: f1(x)=x103f^{-1}(x) = \sqrt[3]{x - 10}
