=+c. Imagine the same procedure for labeling each bundle in your graph; that is, for each bundle, determine what bundle on the 45-degree line is indifferent and label the bundle with the distance on the 45-degree line from (0,0) to the indifferent bundle. The result is a function u1x1

,x2 2 that assigns to every bundle a number. Can you explain how this function meets our definition of a utility function?
