Key Concepts

Analysis of Rational Functions

Rational functions, which are quotients of polynomials, often possess discontinuities and asymptotic behaviors that require careful analysis. Techniques such as factoring and considering the behavior of the numerator and denominator separately help in determining limits, particularly when one-sided or infinite limits are involved.

One-Sided Limits

A one-sided limit examines the behavior of a function as the variable approaches a specific value from one side (either from the left or the right) only. This is crucial for understanding functions that may behave differently depending on the direction of approach since discontinuities or asymptotic behavior can occur uniquely from one side.

Infinite Limits

Infinite limits occur when the magnitude of a function increases or decreases without bound as the variable approaches a particular point. This concept is key in identifying cases where the function approaches positive or negative infinity rather than settling at a finite number, often indicating the presence of vertical asymptotes.

Vertical Asymptotes

Vertical asymptotes occur at points where a function's denominator approaches zero while the numerator remains nonzero, resulting in the function's values growing without bound. Recognizing vertical asymptotes is essential when analyzing the limiting behavior of rational functions near points of discontinuity.
