Determine the domain of the function 9x/ x(x^2-49)

Step-by-step explanation:                  

                                                                       9

The given function may be reduced to , x ≠ 0 because we cannot

                                                                  x^2 - 49  

division by zero in the original form of the function is undefined.  Furthermore, x cannot be either ±7, for the same reason.

Thus, the domain of this function h(x) is {x ≠ 0, x ≠ ±7}

whats the question?
