Question

Q#2 Graph the relation in the table.Then use the vertical-line test.Is the relation a function

Answer 1

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.

Answer 2

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.
