Algebra-1

To determine which number is not an element of the range, we need to identify all unique y-values (second elements of the ordered pairs) from the given points on the graph:

{(−5,4),(−8,4),(−2,4),(2,4),(4,2),(6,0)}

The y-values (range) are 4,2,0.

Thus, the numbers 0,2,4 are all elements...
