Answer:
{-3,-1,1,2,4}
Step-by-step explanation:
We are given that a discrete graph defined on the set of points
{(-3,5),(-1,3),(1,1),(2,4),(4,0),(4,3) and (4,5)}
We have to find the domain of the relation.
Relation : It is defined as the relation between x and y.
The ordered pair (x,y) represents the relation between x and y.
Domain of relation:Set of values of x
Range of relation:Set of values of y
To find the domain of relation we will make the set of values of x.
Set of values of x={-3,-1,1,2,4}
Domain of relation=Set of values of x
Domain of relation={-3,-1,1,2,4}
Hence, option A is true.
