Is the relation a function?
Not every relation is a function. But every function is a relation. Function is just a part of relation.
In a relation the input is the number of people and the output is the number of phones. Is this relation a function Why or why not?
Yes, this relation is a function because each input (number of people) corresponds to exactly one output (number of phones). In other words, for every specific number of people, there is a unique number of phones associated with that quantity, ensuring that no input has multiple outputs. This satisfies the definition of a function.
Why is every function a relation?

Is zero a unique number?
Every number is a unique number.
Every real number has a unique cube root?

Is all relation a function?
Not every relation is a function. A function is type of relation in which every element of its domain maps to only one element in the range. However, every function is a relation.
How do you determine if a relation is a function?
A relation is a function if every input has a distinct output.
Is every relation a function?
No, not every relation is a function. In order for a relation to be a function, each input value must map to exactly one output value. If any input value maps to multiple output values, the relation is not a function.

What is a Primary key in relation to functions and relations?
A primary key is the identifier in a table. It cannot contain values that are null, and it has to be unique for every record. For example, a driver's license number could be a primary key in a relational database table. Every driver is assigned to one unique identifier, or driver's license number, and no two driver's license numbers are identical.
Characteristics of relations in relational database model?
No Duplicate Tuples - A relation cannot contain two or more tuples which have the same values for all the attributes. i.e., In any relation, every row is unique. • Tuples are unordered - The order of rows in a relation is immaterial. • Attributes are unordered - The order of columns in a relation is immaterial. • Attribute Values are Atomic - Each tuple contains exactly one value for each attribute. It may be noted that many of the properties of relations follow the fact that the body of a relation is a mathematical set.
