Mapping Diagram
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 domain and range are two different sets associated with a relationship or function. There is not a domain of a range.
FromA function is a relation between a given set of elements called the domain and a set of elements called the co-domain. The function associates each element in the domain with exactly one element in the co-domain. The elements so related can be any kind of thing (words, objects, qualities) but are typically mathematical quantities, such as real numbers.An example of a function with domain {A,B,C} and co-domain {1,2,3} associates A with 1, B with 2, and C with 3. An example of a function with the real numbers as both its domain and co-domain is the function f(x) = 2x, which associates every real number with the real number twice as big. In this case, we can write f(5) = 10.

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.

For every element on the domain, the relationship must allocate a unique element in the codomain (range). Many elements in the domain can be mapped to the same element in the codomain but not the other way around. Such a relationship is a function.
A diagram that links elements of the domain and range.
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.
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.

The domain and range are two different sets associated with a relationship or function. There is not a domain of a range.
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.
FromA function is a relation between a given set of elements called the domain and a set of elements called the co-domain. The function associates each element in the domain with exactly one element in the co-domain. The elements so related can be any kind of thing (words, objects, qualities) but are typically mathematical quantities, such as real numbers.An example of a function with domain {A,B,C} and co-domain {1,2,3} associates A with 1, B with 2, and C with 3.

In this case, we can write f(5) = 10.
The diagram should be divided into to parts, the domain and the range. The domain is those things that you put into the possible function and the range is what comes out. Let's call a member of the domain x and of the range y. You can tell it is a function by tracing from each x to each y. If there is only one y for each x; there is only one arrow coming from each x, then it is function!
It is the function for which all the elements of the range of the function corresponds to exactly one element of the domain.
A function is a relationship that is one-to-one or many-to-one but not one-to-many. Thus, if a and b are in the domain of the function, then their images in the range, f(a) and f(b) MUST be equal.
If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
