Learn what the end behavior of a polynomial is, and how we can find it from the polynomial's equation. In this lesson, you will learn what the "end behavior" of a polynomial is and how to …

Sal explains what "end behavior" is and what affects the end behavior of polynomial functions.

Analyze polynomial functions to determine how they behave as the input variable increases to positive infinity or decreases to negative infinity.

It'll show you what's the behavior, what value is this function approaching, as x becomes really positive or x becomes really negative. Well, let's just think about it.

Sal picks a function that has a given end behavior based on its graph. Created by Sal Khan.

Finding the end behavior To find the end behavior of a function, we can examine the leading term when the function is written in standard form. Let's write the equation in standard form.

Given a rational function, determine how it behaves as x approaches +∞ or -∞.

Knowing the sign of a polynomial function between two zeros can help us fill in some of the gaps. In this article, we'll learn how to determine the intervals over which a polynomial is positive or …

What is "end behavior" when it comes to polynomials? The end behavior of a polynomial tells you what the polynomial "looks like" as it approaches positive and negative infinity.

End Behavior is essentially the value a function approaches as it moves closer to positive or negative infinity. For example, a linear function F (x) = 3x would approach infinity as x …
