1. A rational function where the degree of the numerator is equal to the degree of the denominator has a horizontal asymptote at where is the lead coefficient of the numerator polynomial and is the lead coefficient of the denominator polynomial.

2. A rational function has a vertical asymptote at every vertical line where is a zero of the denominator polynomial. Set the denominator polynomial equal to zero and solve for all real roots.
