We suspect that the amount you eat (as measured by number of calories) affects happiness in a nonlinear way: those who eat very little will not be happy, those who eat a good amount will be happy, and those who eat a whole lot will not be happy. If we are correct, what form will the model take? A) HAPPINESS = constant + # (CALORIES) - # (CALORIES)² B) HAPPINESS = constant - # (CALORIES) + # (CALORIES)² C) HAPPINESS = constant + # (CALORIES) + # (CALORIES)² D) HAPPINESS = constant - # (CALORIES) - # (CALORIES)²
