Write the rational functions: a) There is a zero at 2, a hole exists at x=-1, vertical asymptote is at x=2, and horizontal asymptote is at y=2 b) There is a zero at -3, a hole exists at x=-4, no vertical asymptotes, and an oblique asymptote at y=x-6 c)The zeros are at -4 and 5 and the vertical asymptote is at x=0. The horizontal asymptote is at y=0 d) the zero is at 2, the vertical asymptote is at x=3 and x=1, and horizontal asymptote is at y=0
