Identify the mapping diagram that represents the relation and determine whether the relation is a function.
{(–2, –5), (–1, –3), (–2, 6), (5, 7)}
The mapping diagram that represents the relation is:
-2 -> (-5, 6)
-1 -> -3
5 -> 7
To determine if the relation is a function, we need to check if each input (x-coordinate) has only one output (y-coordinate).
From the mapping diagram, we can see that the input -2 is associated with two different outputs (-5 and 6). Therefore, this relation is not a function.
