End Behavior of Functions
End behavior refers to the behavior of a function as the input values approach positive or negative infinity. For transcendental functions like exponential functions, understanding end behavior helps predict how the function behaves far away from the origin. This is crucial for sketching graphs and identifying asymptotes.
Limits are fundamental in calculus, used to describe the value that a function approaches as the input approaches a certain point. In the context of end behavior, limits at infinity help determine the horizontal asymptotes of a function. For the function f(x) = -3e^(-x), evaluating the limit as x approaches infinity reveals its behavior.
Asymptotes are lines that a graph approaches but never touches. They can be vertical, horizontal, or oblique. For the function f(x) = -3e^(-x), identifying horizontal asymptotes involves analyzing the limits at infinity, which indicates the value the function approaches as x becomes very large.
