Answer:
The bottom choice.
Explanation:
Evaluate the behavior relating to when x goes into the negatives (-∞), f(x) goes towards the positives or negatives.
Do the same for when x goes into the positives (∞).
So, as x approaches -∞, f(x) approaches -∞ because f(x) goes deeper into the negatives.
And, as x approaches ∞, f(x) approaches -∞ as well, meaning that your answer is the bottom choice.
