To find the inverse function of \( f(x) = x^3 - 13 \), we can start by setting \( y = f(x) \), which gives us \( y = x^3 - 13 \). To solve for \( x \), we rearrange this to get \( x^3 = y + 13 \), and then take the cube root of both sides, leading us to \( x = \sqrt[3]{y + 13} \). Thus, the inverse function is: \[ f^{-1}(x) = \sqrt[3]{x + 13} \] Now, filling in the blanks, we have: \(\left.f^{-1}(x)=\sqrt[3]{x+13}\right)\)
