To find the inverse of the function \( f(x) = 5x^4 \), we need to follow these steps:
-
Replace \( f(x) \) with \( y \): \[ y = 5x^4 \]
-
Swap \( x \) and \( y \): \[ x = 5y^4 \]
-
Solve for \( y \): \[ y^4 = \frac{x}{5} \] \[ y = \left( \frac{x}{5} \right)^{1/4} \]
-
Therefore, the inverse function is: \[ f^{-1}(x) = \left( \frac{x}{5} \right)^{1/4} \]
None of the provided responses accurately reflect this inverse function.
