Looking at the graph of the rational function, we are interested in determining the behavior of the function $f(x)$ as $x$ approaches $-3$ from the left ($x \to -3^-$).

From the graph, it appears that as $x$ approaches $-3$ from the left, the value of $f(x)$ decreases without bound. This indicates that $f(x) \to -\infty$ as $x \to -3^-$.

Thus, the correct statement is:

$\text{As } x \to -3^-, \ f(x) \to -\infty.$

Would you like further details or explanation on this?

Here are five questions that could expand on this topic:

1. What is the behavior of $f(x)$ as $x \to -3^+$?
2. Can we describe the behavior of $f(x)$ at other asymptotes?
3. How do vertical asymptotes influence the behavior of rational functions?
4. How would the graph behave if there were a horizontal asymptote?
5. What changes if we approach a different vertical asymptote, like $x = 3$?

Tip: Always observe vertical asymptotes to understand the behavior of a function as $x$ approaches certain critical values.
