Q)
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. In terms of diet and weight, interpret the statement f(1850) = 158. For this person, decreasing calorie intake by 1850 Calories per day will make his/her weight decrease to 158 pounds. For this person, increasing calorie intake by 1850 Calories per day will make his/her weight decrease to 158 pounds. For this person, consuming 1850 Calories per day results in a weight of 158 pounds. For this person, decreasing calorie intake by 1850 Calories per day will make his/her weight increase to 158 pounds. For this person, increasing calorie intake by 1850 Calories per day will make his/her weight increase to 158 pounds. In terms of diet and weight, interpret the statement f'( 2300) = 0. For this person, his/her minimum weight is attained when they consume 2300 Calories per day. For this person, consuming 2300 Calories per day causes neither weight loss nor weight gain. For this person, his/her maximum weight is attained when they consume 2300 Calories per day. For this person, decreasing calorie intake by 2300 Calories per day causes neither weight loss nor weight gain. For this person, increasing calorie intake by 2300 Calories per day causes neither weight loss nor weight gain. In terms of diet and weight, interpret the statement f -1 (165) = 2000. For this person, increasing calorie intake by 2000 Calories per day will make his/her weight decrease to 165 pounds. For this person, increasing calorie intake by 2000 Calories per day will make his/her weight increase to 165 pounds. For this person, decreasing calorie intake by 2000 Calories per day will make his/her weight decrease to 165 pounds. For this person, consuming 2000 Calories per day results in a weight of 165 pounds. For this person, decreasing calorie intake by 2000 Calories per day will make his/her weight increase to 165 pounds. What are the units of f'(c) = dW/dc pounds/(Calories/day) (Calories/day)/pounds pounds Calories/day none of these
Explanation / Answer
a)For this person, consuming 1850 Calories per day results in weight of 158 pounds
For this person, cosnuming 2300 Calories per day causes neither weight loss nor weight gain
For this person, consuming 2000 Calories per day results in weight of 165 pounds
b) pounds/ (Calories/day)
