Math Problem Statement

Inverse of f(x)=x^3

Solution

To find the inverse of the function f(x)=x3f(x) = x^3, we need to solve for xx in terms of yy, where y=f(x)y = f(x).

Steps:

  1. Start with the equation: y=x3y = x^3
  2. To find the inverse, solve for xx in terms of yy. Take the cube root of both sides: x=y3x = \sqrt[3]{y}
  3. Therefore, the inverse function is: f1(x)=x3f^{-1}(x) = \sqrt[3]{x}

Thus, the inverse of f(x)=x3f(x) = x^3 is f1(x)=x3f^{-1}(x) = \sqrt[3]{x}.

  2. How do you verify that two functions are inverses of each other?
  3. What is the geometric relationship between a function and its inverse?
  4. How does the inverse function behave with respect to odd and even functions?
  5. How does the derivative of f(x)=x3f(x) = x^3 compare to its inverse function?

Tip: To verify if a function and its inverse are correct, check if f(f1(x))=xf(f^{-1}(x)) = x and f1(f(x))=xf^{-1}(f(x)) = x.
