Answer
As $x\to -{{3}^{-}}$ , $f\left( x \right)\ \to \ -\infty $
Work Step by Step
We see that there is an asymptote at $x\ =\ -3$.
The limit $x\ \to \ -{{3}^{-}}$ implies the left-hand side of $x$ as $x$ approaches $-3$.
Therefore, from the graph as $x\ \to \ -{{3}^{-}}$ , $f\left( x \right)\ \to \ -\infty $.
