Answer 2

Answer: Choice A)
x = -5, -3, 1, 2, 6

-----------------------------------------------------------------

Step-by-step explanation:

The domain is the set of allowed inputs of a relation or function. All you have to do is list the values in the "input" oval. Those values are -3, 2, -5, 1, 6 when we read from the top down. Sort them to get -5, -3, 1, 2, 6 which is what choice A says.

Another way is to look at choices B through D. Notice they have -9 in them. The value -9 is not in the input oval (but in the output oval). So we can eliminate B through D. Leaving the only answer of choice A
