To find the inverse of the function \( f(x) = x^3 - 3 \), we need to follow these steps:
-
Replace \( f(x) \) with \( y \): \[ y = x^3 - 3 \]
-
Solve for \( x \) in terms of \( y \): \[ y + 3 = x^3 \] \[ x = (y + 3)^{1/3} \]
-
Replace \( y \) with \( x \) to write the inverse function: \[ f^{-1}(x) = (x + 3)^{1/3} \]
Among the given responses, the correct form of the inverse function is: \[ f^{-1}(x) = \sqrt[3]{x + 3} \]
So, the correct answer is: f^{-1}(x) = \sqrt[3]{x + 3}.
