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
The relation is not a function because the input value -7 is associated with two different output values (-5 and 2).
