Identify the mapping diagram that represents the relation and determine whether the relation is a function.
{(-7,-5),(-4,3),(-7,2),(8,4)}
The mapping diagram that represents the relation is:
-7 -> -5, 2
-4 -> 3
8 -> 4
To determine if the relation is a function, we need to check if each input value (x-coordinate) corresponds to only one output value (y-coordinate).
In this case, we observe that -7 maps to both -5 and 2. Therefore, the relation is not a function.
