Examine the graphs in Exercise 14-26.
In exercise
Select the graph (A through K) that best matches the numbered (1 through 6) descriptions of various cost behavior. For each graph, the vertical (y) axis represents total dollars of cost, and the horizontal (x) axis represents output units during the period. The graphs may be used more than once.

Required:
Using the letters (A through J) as reference points, which graph(s) depict a (1) purely variable cost (i.e., no fixed component), (2) purely fixed cost (i.e., no variable component), or (3) mixed cost (i.e., both a variable and a fixed component).
