Calculate the surface integral for the given surface and function

### Problem 18

Consider the surface defined by the equation:

\[ z = 4 - x^2 - y^2 \]

This equation describes a paraboloid. The constraint on \( z \) is given by:

\[ 0 \leq z \leq 3 \]

Within these bounds, an additional function is defined:

\[ f(x, y, z) = \frac{x^2}{4 - z} \]

In this scenario, you are tasked with exploring the function \( f(x, y, z) \) over the specified surface and range of \( z \). Analyze how the function behaves as \( z \) approaches its bounds, and explore the implications or applications within this context. Consider visualization techniques, such as creating a graph of the paraboloid or mapping the behavior of \( f(x, y, z) \), to better understand these relationships.
