To determine which number is not an element of the range from the given points: {(1,−3),(1,−5),(−5,1),(−8,4),(2,7)}

We need to identify all unique y-values (second elements of the ordered pairs): The y-values (range) are −3,−5,1,4,7.

Now, let's check which number is not an element of the range: <...
