A laboratory study investigating the relationship between diet and weight in adult humans found that the weight of a subject, W (in pounds), was a function W=f(c), of the average number of calories per day, c, consumed by the subject.Suppose we know that f(4500)=0.5. Which of the following statements is the best interpretation of this data?Group of answer choicesIf a typical adult eats about 4500 calories per day on average, that adult will gain about 0.5 pounds per day.If a typical adult eats about 4500 calories per day on average, that adult will lose about 0.5 pounds per day.A typical adult should consume about half of 4500 calories to maintain constant weight.If a typical adult starts eating 4500 calories, it takes about half a day to start gaining weight.
