what is the end - behavior of this function? as x→+∞, then y→ as x→−∞, then y→ done

Explanation:

Step1: Analyze right - hand end behavior

As (x) approaches (+\infty), we observe the graph. The graph is going downwards. So (y\to-\infty).

Step2: Analyze left - hand end behavior

As (x) approaches (-\infty), we look at the left - most part of the graph. The graph is going downwards. So (y\to-\infty).

Answer:

As (x\to+\infty), then (y\to-\infty); As (x\to-\infty), then (y\to-\infty)
