Answer: All Real Numbers Except "-8" (R - {-8})
Step-by-step explanation:
The domain of a function is all possible x values that the function can be defined with.
This means that if a value does not create any indeterminate situation, we can consider this value is in the domain of a function.
For this function, "-8" is not in the domain of the function because the denominator of a rational fraction cannot be zero in any case. This creates an indeterminate situation, therefore we do not consider "-8" in the domain of the function.
But for the other values, there is no problem since the denominator cannot be zero without x = -8.
