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 domain of $g(x) = \frac{1}{x+7}$ excludes values of $x$ that make the denominator zero. Setting $x+7 = 0$ gives $x = -7$, so the domain is all real numbers except $x = -7$.
