Determine which relationship represents a function and which relationship does not represent a function. If there is not enough information, select that response.
Chart 1:
X side in order: 4, 1, 4, 16, 10, -19
Y side in order: -20, -17, 14, 5, 0, -16
Chart 2:
X side in order: -15, -11, -14, -9, -1, -5
Y side in order: 18, 18, 18, 18, 18, 18

Chart 1 represents a function because each x-value is associated with only one y-value. Chart 2 does not represent a function because the x-values are repeated, meaning there are multiple y-values associated with each x-value.
