What are two ways to determine whether a relation is a function?
Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
What is a diagram that shows the relationship of elements in the domain to the range of a function?
Mapping Diagram
Which term defines a relation?
A mapping.
How would you use domain and range to determine whether a relation is a function?
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.
In a mapping diagram how many ordered pairs are there for every row?
The answer is 1

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

What is the function of relation domain and range in mathematics?
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.
When a relation is not 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.
What is the difference between relations and functions?
A function is a relation whose mapping is a bijection.
What is an input or output relation that has exactly one output for each input?
A one-to-one function, a.k.a. an injective function.
What is a relation with the property that for each input there is exactly one output?
That's a proper function, a conformal mapping, etc.
Which relation are function relation?
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.
What makes a relation a function?
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.
