Find the horizontal asymptote(if there is one) using the rule for determining the horizontal asymptote of a rational function for (x^2+x-12)/ (x^2 -4)

2. Relevant equations

3. The attempt at a solution

the degree of the numerator and denominator are both 2.

Y=(An)/(Bn)

Y=1/1

Y=1

When I do the math, the horizontal asymptote is the line y=1.

However when I graph this equation on a TI- 84 plus graphing calculator, if i use the trace, or table functions, the part of the graph that does not appear to cross the line y=1, does. Why is this?
