Answer:
(a) D: {-5, 0, 4, 6}; R: {-9, 0, 9, 13}
Step-by-step explanation:
The domain is the list of values in the x-column.
The range is the list of values in the y-column.
It is useful, but not essential, that the values be listed in numerical order.
x-values are 4, 6, 0, -5, so we can say the domain is {-5, 0, 4, 6}
y-values are 9, 13, 0, -9, so we can say the range is {-9, 0, 9, 13}
