In order to have a vertical asymptote at the denominator polynomial must have a factor of . In order to have a vertical asymptote at , the denomiator polynomial must have a factor of . In order for the function to have a zero at , the numerator must have a factor of , so:



You can multiply the denominator binomials yourself. Since the degree of the denominator polynomial is greater than the degree of the numerator polynomial, there is a horizontal asymptote at .

In order for there to be a hole at -3, both the denominator and numerator polynomials must have a factor of , so:



The degree of the denominator is still greater than the degree of the numerator, so you still have a horizontal asymptote of . Multiplying the binomials to expand the polynomials in your numerator and denominator is left as an exercise for you.
