Question 241950
(8x^2) / (2x^2 - 2)
domain: all real numbers except x=1, x=-1 because those would cause division by zero which is not allowed.
vertical asymptotes: x=1, x=-1
horizontal asymptote: when the powers of the leading number of the numerator and denominator are equal then divide the leading coefficients to find the horizontal asymptote.  8/2=4
