7. increasing int(s): decreasing int(s) end behavior: as x→∞, f(x)→ ________ as x→−∞, f(x)→ ________

Explanation:

Step1: Analyze right - hand end behavior

As (x\to\infty), looking at the graph, the function values are going downwards. So (f(x)\to-\infty).

Step2: Analyze left - hand end behavior

As (x\to-\infty), looking at the graph, the function values are going downwards. So (f(x)\to-\infty).

Answer:

As (x\to\infty), (f(x)\to-\infty) As (x\to-\infty), (f(x)\to-\infty)
