well, the function is 1/3 x, and it looks to be defined at right hand values from i=1 to 3

B has no width for areas of rectangles to sum up .... thought it said A the first time
and C says 2/3 x, which is not what our line equation/function is
we want the answer to include: 1/3 x, delta x, and i from 1 to 3
