Could you please help me with this question and its patrs with explaning ? THANK YOU

Solution

a) II, III has horizontal asymptotes y = 1

b) Only I, Since the polynomial in the numerator is a lower degree than the denominator, the horizontal asymptote is located at y=0.

c) II and III

d) Only I is odd function

e) Only III, as x^2 - 1 = 0 ======> x = +1, -1 vertical asysmptotes
