what is relation in math?
Answers
Step-by-step explanation:
A relation is a relationship between sets of values. In math, the relation is between the x-values and y-values of ordered pairs. The set of all x-values is called the domain, and the set of all y-values is called the range.
In this image, we can see that the domain consists of the x-values from each ordered pair. The range consists of the y-values from each ordered pair. The brackets are used to show that the values form a set. It is important to not repeat values in the domain and range sets (notice that two of the ordered pairs have the number 2 as the y-value, but 2 is listed only once in the range). In this example, the values in the domain and range are listed numerically. While this is common practice, it is not essential.
Answer:
A connection between the elements of two or more sets is Relation
Let A and B be two sets such that A = {2, 5, 7, 8, 10, 13} and B = {1, 2, 3, 4, 5}. Then,
R = {(x, y): x = 4y – 3, x ∈ A and y ∈ B}
R = {(5, 2), (10, 3), (13, 4)}
