The domain is the set of all possible values of x for which the value f(x) exists (is defined). $f(x)$ is defined only for those x which do not produce 0 in the denominator. So, excluded from the domain of real numbers are those x for which $x^{2}-36=0$ $x^{2}=36$ $x=\pm 6$ In interval notation, the domain is $(-\infty,6)\cup(-6,6)\cup(6,\infty)$
