Question

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

Answer 1

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}
