Let's analyze each relationship to determine if they describe a function.
1. **Length of a movie as a function of the number of actors:**
In this case, the length of a movie (in hours) is not determined solely by the number of actors. A movie could have many different lengths regardless of whether it has a few actors or many actors. For instance, a short film could have a few actors, and an epic movie could have numerous actors, yet both might be of different lengths.
**Conclusion:** This relationship does not describe a function.
2. **Amount of milk in pints as a function of the amount of milk in gallons:**
Since there are 8 pints in 1 gallon, we can express the number of pints as a function of the number of gallons. Specifically, the relationship can be represented by the equation:
\[
\text{Number of pints} = \text{Number of gallons} \times 8
\]
For each specific amount of gallons, there is a corresponding specific amount of pints (e.g., 1 gallon = 8 pints, 2 gallons = 16 pints, etc.).
**Conclusion:** This relationship does describe a function.
To summarize:
- Movie length vs. number of actors: **Not a function**
- Milk in pints vs. milk in gallons: **Is a function**
