The degree is even and the leading coefficient is negative.

The degree is odd and the leading coefficient is positive.

The degree is odd and the leading coefficient is negative.

Using limits, the correct statement is given by:

The degree is odd and the leading coefficient is negative.

How the end behavior of a function f(x) is found?

It is found by it's limits as x goes to infinity. On the left, it is given by:

[tex]\lim_{x \rightarrow -\infty} f(x)[/tex]

On the right, it is given by:

[tex]\lim_{x \rightarrow \infty} f(x)[/tex]

Since it is a limit as x goes to infinity, we only consider the term with the highest degree and it's leading coefficient.

Hence, the behavior described, that is, [tex]\lim_{x \rightarrow -\infty} = \infty, \lim_{x \rightarrow \infty} = -\infty[/tex] happens when:

The degree is odd and the leading coefficient is negative.
