function
not a function

Explanation:

Step1: Recall function definition

A function is a relation where each element in the domain is paired with exactly one element in the range.

Step2: Analyze Relation 1

In Relation 1, the domain elements \(v\), \(e\), \(c\) all map to "leaf". Each domain - element has a unique range - element (even though the range - element is the same for all domain - elements). So, it is a function.

Step3: Analyze Relation 4

In Relation 4, the domain element \(1\) is paired with both \(3\) and \(9\). Since an element in the domain (\(1\)) is paired with more than one element in the range, it is not a function.

Answer:

Relation 1: Function
Relation 4: Not a function
