To find the domain of this function, find which values of 'x' is this function valid. Since it is a rational polynomial function, the function is continuous exception for points where the function is undefined.
The function is undefined when the denominator is 0. Solving the polynomial for 0, we can get the values of 'x' where it is undefined:
x^2-64 = 0 ----------> (x+8)(x-8) = 0, thus x = 8, -8
Therefore, the domain is from negative infinity -> infinity expcept for the values of x = 8 and -8
Hope this helps

All real numbers where x is not equal to 8 or -8

JSAM is correct!!!
SET NOTATION FORM:
(-infinity,-8) u (-8,8) u (8,infinity)
