Choose the situation that represents a function. The number of raisins in an oatmeal raisin cookie is a function of the diameter of the cookie. The inches of rainfall is a function of the day's average temperature. The time it takes to cook a turkey is a function of the turkey's weight. The number of sit-ups a student can do in a minute is a function of the student's age.

Answer: The time is takes to cook a turkey is a function of the turkey's weight.

In a function, there is an input and there is an output. The idea of a function is that each individual input is changed into an output.

The time it takes to cook a turkey depends on the size of the turkey.

Smaller turkeys would take less time to cook and larger turkeys would take longer to cook.

So if you start with the turkeys weight, you could determine how long it would need to cook. This is an example of a function.
