Question

The function y=128−8x models the amount of water, in ounces, left in Tariq’s water jug after pouring x servings of water. Which of the following statements properly interprets a key feature of the model?(1 point) Responses Each serving consists of 128 ounces of water. Each serving consists of 128 ounces of water. Before any servings are poured, the jug contains 128 ounces of water. Before any servings are poured, the jug contains 128 ounces of water. Each serving increases the total water in the jug by 8 ounces. Each serving increases the total water in the jug by 8 ounces. Before any servings are poured, the jug contains 8 ounces of water.

Answer 1

The correct interpretation of a key feature of the model \( y = 128 - 8x \) is:

Before any servings are poured, the jug contains 128 ounces of water.

This statement reflects the y-intercept of the function, which is the amount of water in the jug (128 ounces) when \( x = 0 \) (before any servings are poured). The other statements are not accurate interpretations of the model.
