This section explains how to identify slant (oblique) and horizontal asymptotes in rational functions based on the degrees of the numerator and denominator. When the degree of the numerator is exactly one more than that of the denominator, the graph will exhibit a slant asymptote. The section also covers the conditions for horizontal asymptotes, detailing how to determine them based on the relationship between the degrees of the numerator and denominator. Practice problems are provided for further understanding.

Definition If the degree of the numerator is exactly one more than the degree of the denominator then the graph has a slant (oblique) asymptote
Horizontal Asymptotes Horizontal Asymptotes are found by comparing the degrees of N(x) and D(x) a. If n<d the line y=0 is a horizontal asymptote b. If n = d the line is a horizontal asymptote c. If n > d the graph has no horizontal asymptote
