Answer:
The correct option is 1.
Step-by-step explanation:
The set of input values is called domain and the set of output values is called range. In other words the set of x values is called domain and the set of y values is range.
From the given table it is clear that the set of x values with distinct elements is {-1,0,4}, therefore the domain of the relation is
The set of y values with distinct elements is {2,3,4,7}, therefore the range of the relation is
Therefore the correct option is 1.
