Answer:
domain: {3, 5, 7, 11, 13, 15}
range: {-18, -2, 0, 8, 14}
yes, it is a function
Explanation:
The domain is the list of numbers in the x column: {3, 5, 7, 11, 13, 15}.
The range is the list of numbers in the y column. Usually duplicates are removed. It is often useful to order the numbers, but is not strictly necessary. The range is {-18, -2, 0, 8, 14}.
No x-value is repeated, so the relation IS A FUNCTION.
