Final answer:
A "find vertical and horizontal asymptotes" calculator is used to determine the limits of a function as x approaches infinity and to find the vertical and horizontal asymptotes of the function.
Step-by-step explanation:
A "find vertical and horizontal asymptotes" calculator is used in mathematics to determine the limits of a function as x approaches infinity and to find the vertical and horizontal asymptotes of the function. It does not ascertain the intersection points of the function, the points where the function is undefined, or the number of roots of the function.
