vertical asymptote = 8 and -8
horizontal asymptote = 0
slant asymptote = does not exist

Explanation:

  • To work out the vertical asymptote we let the denominator = 0 and solve for x
    x^2-64=0
    x^2=64
    x=+-sqrt64
    x=8, x=-8

  • For the horizontal asymptote, since the degree of the denominator is greater than the degree of the numerator- that is, x^2>x, the horizontal asymptote is simply y = 0

  • Lastly, to work out the slant asymptote, since the degree of the numerator is not greater than the degree of the denominator ( x < x^2) there is no slant asymptote.
