Calculus

## Definition

End behavior describes how a function behaves as the input approaches positive or negative infinity. It characterizes the long-term trend of a function's graph.

## Description

Understanding end behavior is crucial in calculus and its applications, particularly in analyzing long-term trends and making predictions. In fields like economics, end behavior helps forecast long-term market trends; in physics, it's used to understand the limits of physical systems; and in engineering, it's essential for designing systems that remain stable over time. End behavior is closely related to the concept of limits at infinity and asymptotes.

In mathematics education, studying end behavior helps students develop a deeper understanding of function behavior and limits. It's a key concept for graphing functions accurately and for understanding the long-term implications of mathematical models. This knowledge is particularly important when working with polynomial, rational, exponential, and logarithmic functions, as each of these function types can exhibit different end behaviors.

Teacher's Script: "Imagine you're analyzing the growth of a population over time. If we model this with a function P(t), where P is the population and t is time, what happens as t gets very large? Does the population keep growing indefinitely, or does it level off? This is what we mean by end behavior. Let's look at different function types and discuss how we can determine their end behavior. For example, with a quadratic function like f(x) = x^{2}, what happens as x approaches positive or negative infinity? How does this differ from the end behavior of an exponential function like g(x) = 2^{x}?"
