A mapping diagram can be used to represent a function or a relation true or false?
Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
Mapping Diagram
A mapping.
Each element in the domain must be mapped to one and only one element in the range. If that condition is satisfied then the mapping (or relationship) is a function. Different elements in the domain can be mapped to the same element in the range. Some elements in the range may not have any elements from the domain mapped to them. These do not matter for the mapping to be a function. They do matter in terms of the function having an inverse, but that is an entirely different matter. As an illustration, consider the mapping from the domain [-10, 10] to the range [-10, 100] with the mapping defined by y = x2.
The answer is 1

A function is a relation whose mapping is a bijection.
A set of ordered pairs, can also be tables, graphs, or a mapping diagram

A relation is a mapping from elements of one set, called the domain, to elements of another set, called the range. The function of the three terms: relation, domain and range, is to define the parameters of a mapping which may or may not be a function.
A one-to-many mapping (eg square root) Or a relation such as a member of the family. Or a relation such as narrating a story.
A function is a relation whose mapping is a bijection.
A one-to-one function, a.k.a. an injective function.
That's a proper function, a conformal mapping, etc.
A relation is a mapping from one set to another. It is a function if elements of the first set are mapped to only one element from the second set. So, for example, square root is not a function because 9 can be mapped to -3 and 3.
A relation is a mapping between two sets, a domain and a range. A function is a relationship which allocates, to each element of the domain, exactly one element of the range although several elements of the domain may be mapped to the same element in the range.
