Choose the situation that represents a function. The number of raisins in an oatmeal raisin cookie is a function of the diameter of the cool 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.

To determine which situation represents a function, we need to identify a relationship where each input is associated with exactly one output.<br /><br />1. **The number of raisins in an oatmeal raisin cookie is a function of the diameter of the cookie.**<br /> - This may not represent a function because cookies of the same diameter can have different numbers of raisins.<br /><br />2. **The inches of rainfall is a function of the day's average temperature.**<br /> - This does not represent a function because the same average temperature can result in different amounts of rainfall on different days.<br /><br />3. **The time it takes to cook a turkey is a function of the turkey's weight.**<br /> - This represents a function because for a given weight of a turkey, there is typically a specific cooking time recommended (assuming all other conditions are constant).<br /><br />4. **The number of sit-ups a student can do in a minute is a function of the student's age.**<br /> - This does not represent a function because students of the same age can perform different numbers of sit-ups.<br /><br />Therefore, the situation that represents a function is: **The time it takes to cook a turkey is a function of the turkey's weight.**
