![**Finding the Inverse Function Value**
To find \( f^{-1}(a) \) for the function \( f \) and real number \( a \):
### Given:
- **Function**: \( f(x) = x^3 + 5x - 1 \)
- **Real Number**: \( a = 5 \)
### Problem:
Calculate \( f^{-1}(5) \).
### Solution:
The expression requires finding the value of \( x \) for which the function \( f(x) \) equals 5.
The equation to solve is:
\[ f(x) = x^3 + 5x - 1 = 5 \]
By solving this equation, we can determine the correct value of \( x \) which will give us \( f^{-1}(5) \). This value is the solution that needs to be input into the provided blank space.
(You would typically solve the equation either through algebraic manipulation, numerical methods, or using computational tools to find the exact value of \( x \)).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Faf85ad90-fab3-42b7-a16f-d68658bd6ca6%2Febaf3c40-9f4f-4960-b1e4-734ed03142f5%2Fxwtxfun_processed.jpeg&w=3840&q=75)
