Key Concepts

Limit

A limit is a fundamental concept in calculus that describes the value a function approaches as its input gets arbitrarily close to a particular point. Limits help in understanding the behavior of functions near points of interest, even if the function is not defined exactly at those points.

Rational Function

A rational function is a function that can be expressed as the ratio of two polynomials. Evaluating limits of rational functions involves analyzing both the numerator and the denominator, particularly when the denominator may approach zero, which can signal potential discontinuities or asymptotic behavior.

Vertical Asymptote

A vertical asymptote is a line x = a where a function tends to infinity or negative infinity as the input approaches a. It occurs in rational functions when the denominator becomes zero while the numerator remains nonzero, leading to unbounded behavior near that value.

One-sided Limit

One-sided limits involve evaluating the behavior of a function as the input approaches a certain point from one side—either from the left or the right. This concept is especially useful when dealing with vertical asymptotes or other discontinuities, as the function may exhibit different behavior on each side of the point.
