### Analysis of the Function \( f(x) = \frac{x^3}{x^2 - 12} \)

**(a) Domain:**
- The domain of \( f \) is \( (-\infty, -2\sqrt{3}) \cup (-2\sqrt{3}, 2\sqrt{3}) \cup (2\sqrt{3}, \infty) \).

**(b) Asymptotes:**
- **Vertical Asymptotes:** The function \( y = f(x) \) has vertical asymptotes at \( x = 2\sqrt{3} \) and \( x = -2\sqrt{3} \).
- **Horizontal Asymptotes:** The function does not have horizontal asymptotes.
- **Slant Asymptotes:** The function \( y = f(x) \) has a slant asymptote at \( y = x \).

**(c) Symmetry:**
- The function \( y = f(x) \) is an even function.

**(d) Increasing/Decreasing:**
- \( f \) is increasing for \( x \in (-\infty, -6) \cup (6, \infty) \).
- \( f \) is not decreasing for any \( x \).

**(e) Critical Point Classification:**
- \( f \) has a local maximum at \( x = -6 \).
- \( f \) has a local minimum at \( x = 6 \).
- There are no critical points that are neither local minima nor maxima.

**(f) Concavity:**
- The function is not concave up for any \( x \).
- The function is not concave down for any \( x \).

**(g) Inflection Points:**
- There are no inflection points. 

This analysis provides a comprehensive understanding of the behavior of the given function, including its asymptotic behavior, symmetry, and critical points.
