End Behavior • Limits at infinity Graphically Numerically Analytically
Horizontal Asymptotes • Definition • The line y = L is a horizontal asymptote of the graph of f if
Limits at Infinity • If r is a positive rational number and c is any real number, then • Furthermore, if
Guidelines for Finding Limits of Rational Functions • If the degree in the numerator and denominator are the same, the horizontal asymptote is • If the degree in the numerator is smaller than the degree in denominator, the horizontal asymptote is
Guidelines for Finding Limits of Rational Functions • If the degree in the numerator is larger than the degree in the denominator, there is no horizontal asymptote.
