What is the best definition of a relation in math?
The relation, between two sets of objects, is a mapping which associates elements of the first set to those of the second set.
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 is defined as the distance between two points?
The metric of a geometric space is defined as the distance between two points.
What does the word relation mean in math?
A relation is a mapping from one set to another. The two sets may be the same, or different. It is an association between elements (or members) of one set with those of the other set. Some mappings are functions but mappings need not be functions.
Why do functions matter?
Functions are our way of expressing a relation between two sets, which is of fundamental importance to all of math. In fact, one could argue that there would be no math, only numbers, if there weren't any relations between the numbers.

What are the relation that is also a function?
A relation is a mapping between elements of two sets - which need not be different sets. The relationship may be one-to-one or many-to-one but not one-to-many. In graphical form, any line which is parallel to the y-axis can meet the plot at most once.
Is a vertical line a relation in math?
Yes, you can consider it a relation between the points on the x-axis, and the points on the y-axis. In fact, ANY subset of R squared (in other words, any subset of the points on a plane), including the empty set, sets that contain single points, and larger sets, can be considered a relation in R squared (i.e., two sets of real numbers).
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 is the paritisum?
Parasitism can be defined as the relation between two different kinds of organisms in which one receives denifits from the other by causing damage to it. The damage is usually not fatal.
What is the relation between energy and charge?
The relationship between energy and charge is potential difference or voltage. Where a volt is defined as existing between two points in an electric field when one joule of energy is required to move a charge of one coulomb between the two points.
What is defined as the distance between two points?
The metric of a geometric space is defined as the distance between two points.
What for two sets is the set of all elements that are in either set?
The union of a collection of sets is defined as the set of all distinct elements that are in the collection. This includes the specific case where the collection consists of two sets.
What is a mere relation?
A relation is an expression that is not a function. A function is defined as only having one domain per range, meaning that when graphed, a function will have no two points on the same vertical line. If your expression is graphed and two points do appear on the same vertical line, it is a relation, not a function.
What are the requirement that two relation must satisfy in order to be considered union-compatible?
The two result sets bust each have the same number of columns and each pair of columns between the two must be of the same data type.
What relation is between bulimia and dopamine?
The high between the two
Can every rectangle be a parallelogram?
Well, a rectangle is defined as having two sets of parallel sides and four right angles, a parallelogram is defined as having two sets of parallel sides and two sets of supplementary angles. Therefor, a rectangle is always, by definition, a parallelogram. A parallelogram is not always a rectangle, but it can be.
