Answer
Explanation:
Step1: Define the criteria for a function
A relation is considered a function if every element in the domain is paired with exactly one element in the range.
Step2: Analyze the mappings in Relation 1
From the provided diagram for Relation 1:
- The element $a$ maps to $5$.
- The element $w$ maps to $7$.
- The element $k$ maps to $6$.
- The element $c$ maps to $-6$.
Step3: Determine if the relation is a function
Since each element in the domain ${a, w, k, c}$ is associated with exactly one unique value in the range, Relation 1 satisfies the definition of a function.
Answer:
Relation 1
