Use the vertical - line test. If any vertical line intersects the graph at more than one point, it is not a function. In the given graph, a vertical line can be drawn that will intersect the graph at more than one point.

The data set has an out - lier (the value 11). The mean is affected by outliers, while the median and mode are not. The mode is 2 as it appears most frequently, but the median is a better measure of central tendency when there are outliers.

Answer:

b) Not a function
