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. a. For this person, decreasing calorie intake by 1850 Calories per day will make his/her weight decrease to 158 pounds.
b. For this person, increasing calorie intake by 1850 Calories per day will make his/her weight decrease to 158 pounds.
c. For this person, consuming 1850 Calories per day results in a weight of 158 pounds.
d. For this person, decreasing calorie intake by 1850 Calories per day will make his/her weight increase to 158 pounds.
e. For this person, increasing calorie intake by 1850 Calories per day will make his/her weight increase to 158 pounds
From the given condition, W(weight) is a function of C(calories), that is, the value of W is highly dependent on the value of C. In this case, C, is the independent variable and W is the dependent variable. Option C is more correct than other options because the question did not state if increasing C or decreasing C means we havw an increasing W or decreasing W, it only stated that W is. function of C.
Hence when an average of 1850 of calories is consumed, the resulting weight is 158pounds.
so i basically took 12 and added that to 18 [and got 30] to find out how many degrees it went up and then i solved each equation till i got 30. I hope this helped and that you could understand the way i did it.
