Posts: 848 Thanks: 0 A function of this type is undefined when the denominator is equal to zero. If you meant the function to be as written, then its domain is all real numbers except x=0. If, however, you meant 1/(x^2 - 16), then the function is defined for all real numbers except x=4 and x=-4 because x^2 - 16 factors as (x + 4)(x - 4).
