<em><u>Let us understand about domain and range</u></em>
Domain refers to the set of possible input values
Range is the set of possible output values
Thus the input values in given relation are:
(x, y) = (-5, 8) , (4, -2) , (4, 1) , (3, 0)
The input values are values of "x"
Input values = -5, 4, 4, 3
Thus the domain of given relation are -5, 4, 4, 3
Thus option C is correct
