Determine if the set of points (-4,2), (-1,2), (0,2), and (6,2) is a function. Explain.
Hint: Draw a diagram like the ones above and map your inputs to your outputs.
The set of points is not a function because the range consists of the value 2 four times.
The set of points is a function because the range consists of the value 2 four times.
The set of points is a function because each value in the domain corresponds to exactly one value in the range.
