- Function: (1, -2), (2, 1), (3, 6), (4, 13), (5,22)
- Not a function: (7, 4), (5, -1), (3, -8), (1, -5), (3, 6) for the given relation.
<h3>What is defined as the relation and function?</h3>
- Relations and functions describe a mapping between two sets (Inputs as well as Outputs), resulting in ordered pairs of a form (Input, Output).
- Relationship and function are crucial concepts in algebra.
For the given relation is the question;
Case a: (1, -2), (2, 1), (3, 6), (4, 13), (5,22)
In this, the first values are the domain and the second are its range for the respective domain.
In every set of domain and range, every range has the distinct value for its domain.
Thus, the relation is said as function.
Case b: (7, 4), (5, -1), (3, -8), (1, -5), (3, 6)
For the given set of domain and their respective range.
The set (3, -8) and (3, 6) have the same input value of domain, which is not possible for the function.
Two different range cannot have the same function.
Thus, the given relation does not form the function.
