Find the domain.
-$y = \frac { 5 } { x + 15 }$
A) $( - \infty , \infty )$
B) $( - \infty , 15 ) \cup ( 15 , \infty )$
C) $( - \infty , 5 ) \cup ( 5 , \infty )$
D) $( - \infty , - 15 ) \cup ( - 15 , \infty )$

Question

Quizplus · Accepted Answer

The denominator of the fraction cannot be zero, so $x + 15 \neq 0$, which means $x \neq -15$. Therefore, the domain is all real numbers except -15.
