Find the domain and vertical asymptote of g(x) =−log5(x+1) g ( x ) = - \log _ { 5 } ( x + 1 ) g(x) =−log5(x+1) .
A) Domain: (−∞,∞) ( - \infty , \infty ) (−∞,∞) Asymptote: x=−1x = - 1x=−1
B) Domain: (−1,∞) ( - 1 , \infty ) (−1,∞) Asymptote: x=−1x = - 1x=−1
C) Domain: (−1,∞) ( - 1 , \infty ) (−1,∞) Asymptote: y -axis
D) Domain: (0,∞) ( 0 , \infty ) (0,∞) Asymptote: y -axis
E) Domain: (0,∞) ( 0 , \infty ) (0,∞) Asymptote: x=−1x = - 1x=−1
Logarithm
The power to which a base, usually 10 or e, must be raised to produce a given number.
Vertical Asymptote
A line that a graph approaches but never touches, typically representing values that are not included in the domain of a function.
Domain
The set of all possible input values (x-values) for a given function, over which the function is defined.

Final Answer :
B
Explanation :
The argument of the logarithm must be greater than 0, so we have the inequality x+1>0x + 1 > 0x+1>0 which gives us x>−1x > -1x>−1 . Therefore, the domain of g(x)g(x)g(x) is (−1,∞)( - 1, \infty )(−1,∞) . The function g(x)g(x)g(x) has a vertical asymptote at x=−1x = -1x=−1 , which can be seen by taking the limit as xxx approaches −1-1−1 from both sides and observing that the absolute value of the function values grows very large.
