The data in the table represents a company's profit based on the number of items produced. Profit Based on Number of the Items Produced Items Produced x Dollars of profit y 100 negative 70 comma 500 200 50 300 50 comma 100 400 80 comma 300 500 90 comma 400 600 78 comma 000 Which equation best represents the data?

Choice B gives values close to the table’s profits. For example, when x = 300, it predicts y = −1.026(300²) + 1016.402(300) − 162075 = 50,505.6, close to the listed $50,100. At x = 400, it predicts about $80,326, close to $80,300. The small differences are expected because the equation is a best-fit model.
