Answer:
x
(first option listed)
Explanation:
The domain of a function is all possible x-values for that function
So, we can see (from the x-value portion of our table) that the possible x-values are:
-6 , -1, 0, and 3
We write domain and range in lowest - highest number value order, so we write our domain as such:
x = -6, -1, 0, 3
{range is all possible y-values, and this would include -7 , 1, 9, and -2}
hope this helps!!
