Answer:
Option B is correct.
The domain of the function is, {3,4,5,6}
Step-by-step explanation:
A mathematical relationship is given in the table, the independent variables are generally listed in the left hand column, are the domain and the dependent variables usually found in the right hand column, are the Range.
The x-coordinates are the independent variables and the y-coordinates are the dependent variables.
The domain of a function is the complete set of the possible values of the independent variables.
The domain of the function in this table are the first column i.e, {3,4,5,6}
