Answer:

Option D

Explanation:

Given the function
g(x)=(-7(x-5)^2(x+6))/((x-5)(x+5)), we see that
(x-5) appears in both the numerator and denominator which cancel out to be
(-7(x-5)(x+6))/((x+5)). This means that there's a vertical asymptote at
x=-5 for the denominator to be 0.

Additionally, the limit of the function g(x) as x approaches -5 from the left side is -∞. The limit of the function g(x) as x approaches -5 from the right side is ∞. See the attached graph for a visual of these limits.

In conclusion, option D is correct.
