Verified Answer :
The range is the set of y coordinates (or outputs). For any point (x,y) the y coordinate is the second number listed. For example, with (8,7) the y coordinate is 7.
So we simply list all of the y coordinates of each ordered pair. Those values are: 1, 0, -1, 7, 7
Let's order them as you would see on a number line
-1, 0, 1, 7, 7
then let's toss out the extra 7 to get
-1, 0, 1, 7
So the range is the set {-1, 0, 1, 7}
The range of the given relation is {1, 0, -1, 7}.
What is the range of a relation?
The set which contains all the second elements of all the ordered pair of a relation is called the range of relation.
What is the domain of a relation?
The set which conatins all the first elements of all the ordered pairs of relation is known as the domain of the relation.
What is set?
Sets are a collection of well-defined objects or elements.
According to the given question.
We have a set of ordered pairs which shows a relation between the two obects of the set.
{(-2, 1), (0,0), (3, -1), (-1, 7), (5, 7)}
We know that " the set which contains all the second elements of all ordered pairs of a relation is called range of the relation".
Therefore, the range of the given relation is {1, 0, -1, 7}.
