Answer:
R = {-9, -3, 7}
Step-by-step explanation:
The range are all the outputs (y-values) in a given relation or function.
{(4,7), (4, -3), (-5, -9)}
The range in the given set is {-9, -3, 7}.
Hope this helps.
The range is 16 because your lowest value is -9 and your highest value is 7 and you add both of those and that’s how you get 16
