Question

I need help understanding the End Behavior of Polynomial Functions

Answer 1

This follows the function....

f(x) = 3x^2 + 8x - 9x^5

-9x^5 is the one it shows because it has the largest exponent

Odd because the degree of 5 and negative because of...well...the negative sign

I get how to label it and classify it. I can study the drawings so I now how to do it on the quiz. But what I DONʻT GET is the End Behavior.


It says that the end behavior for this is

\[x \rightarrow \infty , y \rightarrow -\infty \]

\[x \rightarrow -\infty , y \rightarrow \infty \]
