The Deep Dive
To find the inverse of the function \( f(x) = 4 + \sqrt[3]{x} \), we start by replacing \( f(x) \) with \( y \): \[ y = 4 + \sqrt[3]{x} \] Next, we solve for \( x \) in terms of \( y \): 1. Subtract 4 from both sides: \[ y - 4 = \sqrt[3]{x} \] 2. Now, cube both sides to eliminate the cube root: \[ (y - 4)^3 = x \] Now, we have expressed \( x \) in terms of \( y \). To write the inverse function, we swap \( x \) and \( y \): \[ f^{-1}(x) = (x - 4)^3 \] Thus, the inverse function is: \[ f^{-1}(x) = (x - 4)^3 \]
