E)all real numbers x except x = -1

Question

Find domain of the following function.​ $$g ( x ) = \frac { 1 } { x + 7 }$$ ​
A)all real numbers x except x = -7
B)all real numbers x except x = 1
C)all real numbers x except x = 49
D)all real numbers x except x = 7
E)all real numbers x except x = -1

Quizplus · Accepted Answer

The denominator of the function cannot be zero, so $x + 7 \neq 0$, which means $x \neq -7$. Therefore, the domain includes all real numbers except $x = -7$.
