A shopkeeper in Jaipur models his daily profit (in hundreds of rupees) as a parabola y = p(x), where x is the number of items sold. The parabola cuts the x-axis at x = 4 and x = 20. At which numbers of items is the profit exactly zero (break-even)?

4 and 20. Profit is zero where y = 0, i.e. where the graph meets the x-axis: at x = 4 and x = 20 items.

A shopkeeper in Jaipur models his daily profit (in hundreds of rupees) as a parabola $y = p (x)$ , where $x$ is the number of items sold.
