Explanation / Answer

7: the domain of the relation is the x cordinates of the points marked on the graph i.e.{-3,-2,0,1,2,4}

8:The domain of the function will be those values of x for which the function is defined .Hence for x>=5 the function is defined. The function takes all positive numbers including zero.So option D is correct

9:the first element of each pair forms the domain and the second element of each apir forms the range .So option C is correct
