What are the vertical and horizontal asymptotes for the function f (x) = (3x^2/x^2-4)

The vertical asymptotes are calculated by solving the equation dominator=0

x^2-4=0

(x-2) (x+2) = 0

x=2 and x=-2 are vertical

The horizontal asymptote is calculated by dividing the leading terms.

3x^2/x^2 = 3

y=3 is horizontal asymptote
