Answer:
The values that are not in the domain of the function h(x) = (x - 3) / x^2 are the values of x for which the denominator, x^2, equals zero, because division by zero is undefined in mathematics.
To find these values, set the denominator equal to zero and solve for x:
x^2 = 0
This equation has only one solution:
x = 0
So, the only value of x that is not in the domain of h(x) is x = 0. All other real numbers are in the domain of the function h(x).
