how can you use a mapping diagram to determine the domain and the range of a relation?
Accepted Solution
A:
Step 1: Draw the mapping diagram for the given relation. Step 2: A relation is a function if each element in the domain is paired with one and only one element in the range. Step 3: From the mapping diagram, it can be observed that the given relation is not a function as '3' in the domain is paired with two elements - 1 and - 2 in the range and '6' is paired with - 1 and - 2.
