Does this table represent a function?why or why not

The answer is C, because there are two different numbers correlated to the same number on the Y side. The table does not represent a function.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
