To determine if a relation is a function, we need to check if each x-value is paired with only one y-value.
In this case, we have the following x and y values:
x: 2, -3, 8, 2
y: 4, 5, 0, 4
For x = 2, we have two y-values: 4 and 4.
Therefore, this relation is not a function because x = 2 is paired with multiple y-values.
Determine whether the following relations are functions
x y
2 4
-3 5
8 0
2 4
