Question 8 • Math 3
For a rational function, compare the degrees of the numerator and denominator. If the numerator’s degree is larger, the function has no horizontal asymptote. In A, the numerator has degree 2 and the denominator has degree 1, so there is no horizontal asymptote. In B, C, and D, the numerator’s degree is no greater than the denominator’s, so each has a horizontal asymptote.
