This article is about the symmetrical reflections of profit and loss functions and the functions obtained from them, which are widely used in economic, economic and financial applications of mathematics. It is seen that the applications in the literature are calculated according to the profit and loss accounts alone. Since the occurrence of loss in an economic activity negatively affects the result of the profit, as a result of the loss, economic activity bankruptcy, etc. decisions are finalized. This has irreversible consequences. The controllability of these two interactive events poses reassuring risks. In short, it enables the manageability of the activity. Applications in life take place on a more real axis. To control, to see the whole event, thus providing the possibility of intervention. Therefore, it started with linear functions in the plane. Evaluations were made on the graphics here.
The system concepts existing in Mathematical Science, their results in applications, especially in economic activities in the market were examined and their symmetrical reflections with respect to each other were examined. Starting from the reflections of the known profit and loss functions, their interactions with each other were investigated [4]. How the break-even point was reflected according to these reflections, and therefore what they did was examined. The reflection of profit and loss functions according to another function was discussed. This makes it necessary for the control, planning and implementation of the situations observed in an economic activity, which are known in market economies. Therefore, it was emphasized that when the price will change in an economic activity, it will be more important to monitor and manage, and even at what stage the advertisements will be made, as a result of reflections. The loss curve is negatively sloping due to price, reflecting new information on the condition of its slope. It was emphasized that the reflections of the determining factors in marketing vary so much. As is known, prices simultaneously reflect both the value for the buyer of the next (or marginal) unit and the cost for the seller of that unit.
