The correct interpretation of the key feature of the model \( y = 128 - 8x \) is:
**Before any servings are poured, the jug contains 128 ounces of water.**
This is because when \( x = 0 \) (indicating no servings have been poured), the amount of water left in the jug is \( y = 128 - 8(0) = 128 \) ounces. The other statements do not accurately describe the function.
