9.3 Practice Test Page 362. Questions: 2 and 3
    
  
The correct answer would be letter "B". If we used that for base 1,2 and 3 it would work. 
Ex: 3 (1) = 3 
       3 (2) = 6
       3 (3) = 9


The graph relates to the letter C on the table of values. It's the answer because the numbers on the table of values are plotted on the graph.
