Find and describe the domain of the function
![The image shows a mathematical function in three variables, \(x\), \(y\), and \(z\). The function is written as:
\[
f(x, y, z) = \frac{x - y}{y^2 + 2y + z^2 - 4}
\]
This represents a rational function where the numerator is the expression \(x - y\) and the denominator is the quadratic expression \(y^2 + 2y + z^2 - 4\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5563205c-2551-4780-a535-119e8d9f322e%2F0dabb4ee-b4e9-4f74-b6d2-50db5c098dac%2F4x7coo4_processed.png&w=3840&q=75)
