Determine whether the relation defines $y$ as a function of $x$. Give the domain.
-$y=\frac{-9}{x+11}$
A) Not a function; domain: $(-\infty,-11) \cup(-11,0)$
B) Function; domain: $(-\infty,-11) \cup(-11, \infty)$
C) Function; domain: $(-11,11)$
D) Not a function; domain: $(-\infty, \infty)$

The relation defines $y$ as a function of $x$ because for each $x$ value, there is exactly one $y$ value. The domain excludes $x = -11$ to avoid division by zero, so the domain is $(-\infty,-11) \cup(-11, \infty)$.
