Susan is taking an Algebra test on functions. Question 10 shows the following list of ordered pairs:

{(–5, 7), (–2, 1), (0, 3), (4, 7)}

Which choice should best explain why the relation IS or IS NOT a function?

Question 2 options:

a function; only one range value exists for each domain value


a function; two domain values exist for range value 7


not a function; the relation does not pass the horizontal line test when all points are graphed


not a function, two domain values exist for range value 7
