Negative Infinity
1. Let's clarify the problem you are asking about involving $-\infty$.
2. If the question relates to a limit or boundary behavior such as $\lim_{x \to a} f(x) = -\infty$, it means as $x$ approaches some value $a$, the function $f(x)$ decreases without bound indefinitely.
3. Negative infinity ($-\infty$) is not a real number but a concept indicating a value that is arbitrarily large in the negative direction.
4. If your question is: Does the limit or value go to $-\infty$? or is the answer $-\infty$? then yes, it means the function or sequence decreases without limit.
5. Please provide the full problem next time to confirm this interpretation and the exact reasoning.
Final answer: It is $-\infty$ if the function or value diverges negatively without bound.
