Answer: As x decreases without bound the graph f(x) decreases, as x increases without bound the graph of f(x) increases.
Explanation:
Since, the given function is ,

If
then

that is, we can say, as x decreases without bound the graph f(x) decreases.
While, If
then

That is, we can say, as x increases without bound the graph f(x) increases.
thus, we can say first option represents the correct end behavior of f(x).
