A rational function can have vertical, horizontal, or slant asymptotes, depending on the degrees of its numerator and denominator. Vertical asymptotes occur when the denominator equals zero, causing the function to approach positive or negative infinity. Horizontal asymptotes are determined by the leading terms of the numerator and denominator, while slant asymptotes result from the ratio of the leading coefficients.

At its core, a rational function is the ratio of two polynomials. It's a mathematical construct that can be represented algebraically as f(x) = p(x)/q(x), where p(x) and q(x) are polynomials. The behavior of a rational function is influenced by its degree, leading terms, and roots. Understanding these elements allows for the analysis of various aspects, such as asymptotes, holes, and limits.
