Use what you learned, back in algebra, aboutasymptotes:

vertical asymptotes: zeroes of the denominator

horizontal asymptotes: the x-axis, if the degree of the numerator is less than the degree of the denomintor; "y = a/b" for leading coefficients "a" and "b", if the degrees are the same.

slant asymptotes: the quotient (ignoring the remainder) of the long division, assuming the numerator's degree is exactly one greater than the denominator's.
