So after reading purplemath.com's lessons about finding asymptotes from equations of rational functions, here's what I've learned. Please correct any mistakes and state any exceptions ... If any.
Thanks a lot!If the degree of the polynomial in the numerator is greater than that in the denominator, then there is a slanted asymptote at y=the quotient of the 2 polynomials.
If the degree of the polynomial in the denominator is greater than that of the numerator, the asymptote is at y=0, or x-axis.
If both degrees are the same, then the asymptote is at y=(numerator leading coefficient) / (denominator leading coefficient).
