Answer

The simplified expression for \( f^{\prime\prime}(x) \) is: \[ f^{\prime\prime}(x) = \frac{-x^2}{(x^2 - 5)^3} + \frac{1}{\sqrt{x^2 - 5}} \]

To fully appreciate the nuances of this equation, let’s talk about where it fits in the grand tapestry of mathematics! This expression is a second derivative, which often has roots in physics, particularly when calculating acceleration from a position function. The acceleration of an object can be modeled as \( f^{\prime \prime}(x) \), giving insight into the object's motion and response to forces. Who knew calculus would be this exciting? Now, when tackling equations involving higher derivatives like this, keep an eye out for common pitfalls. A frequent mistake is overlooking the chain rule when dealing with composite functions in derivatives. Make sure to cleanly apply all rules, and don't forget to check the domain of your function—especially since square roots and fractions can impose tight restrictions on \( x \). Happy calculating!
