For this case we have the following table:
 x     y
 -1     3
  1    -1
  2     2
  1     3
 We observe that the graph shown in the question shows a scattering of points that do not obey any behavior of known function.
 Therefore, the table does not represent any function.
 Answer:
 The table does not represent a function.

The graph of the relation between x and y is as shown in attached figure

By applying the vertical line test we find that the relation is not a function because there are two points which are (1,-1) , (1,3) have the same value of x with different values of y which contradicts with with the rule of function.
