**Problem Statement:**

Set up the triple integral in Rectangular, Cylindrical, and Spherical Coordinate forms (DO NOT INTEGRATE).

**Region D:**
- \( z \leq 0 \) 
- \( x^2 + y^2 + z^2 = 9 \)

\[ \iiint xy^2 + z \, dV = \, \_\_\_\_\_\_? \_\_\_\_\_\_ \]

**Explanation of the Problem:**

The problem asks to set up, but not solve, a triple integral for the function \( xy^2 + z \) over the region \( D \) specified by the conditions:
- \( z \leq 0 \): This indicates the region is below or on the xy-plane.
- \( x^2 + y^2 + z^2 = 9 \): This represents a sphere with radius 3, centered at the origin.

The goal is to express this triple integral in different coordinate systems:
1. **Rectangular Coordinates:** \((x, y, z)\)
2. **Cylindrical Coordinates:** \((r, \theta, z)\) where \( x = r\cos\theta \), \( y = r\sin\theta \), and \( z = z \).
3. **Spherical Coordinates:** \((\rho, \theta, \phi)\) where \( x = \rho\sin\phi\cos\theta \), \( y = \rho\sin\phi\sin\theta \), and \( z = \rho\cos\phi \).

For each coordinate system, determine the bounds of integration according to the described region \( D \).
