Answer:
1 ) B. {-5 , -4 , 2}
2 ) A. {-1 , 1 , 3}
Step-by-step explanation:
1. The range of a relation is an ordered pair of real numbers to which all the real numbers in the domain relate to.
Given the Relation R: { ( 3, -5 ) , ( 1 , 2 ) , ( -1 , -4 ) , ( -1 , 2 ) }
Here The Range is the ordered pair of number towards the right in each relation.
Range = { -5 , 2 , -4 }
2. The domain of a relation is an ordered pair of real numbers which are related to any one of the element in the range of the relation.
Given the Relation R: { ( 3 , -2 ) , ( 1 , 2 ) , ( -1 , -4 ) , ( -1 , 2 ) }
Here the domain is the ordered pair of numbers towards the left in each relation.
Domain = { -1 , 1 , 3 }
