Function.
True.
Relation is one record in the database or a tuple. Relationship is that how tables are connected to each other.
In a symmetric distribution, the mean and the median are the same. Otherwise there is no relation. In symmetric distributions with only one mode, the mode will coincide with the mean and median, but otherwise there is no relation.
A relation is defined as a set of tuples. Mathematically, elements of a set have no order among them; hence, tuples in a relation do not have any particular order. In other words, a relation is not sensitive to the ordering of tuples. Tuple ordering is not part of a relation definition because a relation attempts to represent facts at a logical or abstract level. Many logical orders can be specified on a relation but there is no preference for one logical ordering over another.
A relation has pairs of numbers. A function is a special relation where for each input there is one and only one output.
1. One to One -function- 2. One to Many -relation- 3. Many to Many -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 set of ordered pairs, can also be tables, graphs, or a mapping diagram
A ratio is a comparison of one number in relation to another number. A percent is a comparison of one number in relation to One Hundred.
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.
Function.
one to many; many to one ; one to one
It is an injective relation.
True.
A relation is any set of ordered pairs.A function is a relation in which each first element corresponds to exactly one second element
A relation where each element of the domain is paired with only one element of the range is a one to one function. A one to one function may also be an onto function if all elements of the range are paired.
