Give an example of a case where a cost and a revenue function do not have a break-even point.

Explanation:

Firstly Break even point is a point where revenue equals cost.

A typical example of a scenario where cost and revenue function does not have a break even point includes, when the profit margin of any given company or individual is higher when compared to the losses of the company or individual. For there to exist a break even point, company or individuals sales have to fall considerably such that revenue equals cost( no profit,no loss).
