	3.	In a science experiment, students hung a cup from a spring and measured the length of the spring when candies were added to it. Their data are shown in the table below. Which statement is true?
		A.	The relation is not a function because there are two y values for some x values.
		B.	The relation is a function because the range values increase.
		C.	The relation is not a function because only a line can be a function.
