Answer

Final Answer: The limit of g(x) as x approaches -4 is \(\boxed{-3}\).

Steps

Step 1 :We are given that the function g(x) is bounded by two functions, \(\frac{-2 x-11}{x+5}\) and \(x^{2}+9 x+17\), on the interval (-5,-3).

Step 2 :We need to find the limit of g(x) as x approaches -4. Since -4 is within the interval (-5,-3), we can find the limits of the bounding functions at x=-4 and see if they are equal.

Step 3 :If the limits of the bounding functions are equal, then that is the limit of g(x). If they are not, then the limit of g(x) does not exist.

Step 4 :Let's find the limits of the bounding functions at x=-4. For the function \(\frac{-2 x-11}{x+5}\), the limit as x approaches -4 is -3.

Step 5 :For the function \(x^{2}+9 x+17\), the limit as x approaches -4 is also -3.

Step 6 :The limits of both bounding functions at x=-4 are equal, which means the limit of g(x) as x approaches -4 exists and is equal to the common limit of the bounding functions.

Step 7 :Final Answer: The limit of g(x) as x approaches -4 is \(\boxed{-3}\).
