Question

Which of the following arguments are valid? [At least one of the arguments is valid.] No polynomial functions have horizontal asymptotes. This function does not have a horizontal asymptote. ... This function is a polynomial function. Any function that is a polynomial will not approach a fixed value as its input grows without bound, positive or negative. This function approaches the value 0 as its input grow without bound in both the positive and negative directions. ... This function is not a polynomial No polynomial functions have horizontal asymptotes. This function has a horizontal asymptote. ... This function is not a polynomial function. No polynomial functions have horizontal asymptotes. This function is a polynomial function. This function does not have a horizontal asymptote.
