In business, the break-even point is the point (x, y) at which the graphs of the revenue and cost functions intersect. This is the point where the revenue and the expenses are equal. The business is not losing money, but it is not making money either. For one manufacturing company, the revenue from producing x items is given by the function y = 2x + 12 and the cost of producing x items is given by y = −x2 + 10x + 5. The numbers represent thousands. Find all break-even points. Interpret the results.
