Answer:
{(1, 5.75), (2, 5.50), (3, 5.25)}
Explanation:
x increases from 1 to 2 to 3 .
That <em>eliminates options B and D</em>.
y decreases at a rate of 0.25 gal/min.
At x = 1 min, y will have decreased to 5.75 gal.
That <em>eliminates Option A. </em>
The correct answer is {(1, 5.75), (2, 5.50), (3, 5.25)}.
A graph of <em>volume vs. time</em> using the correct set of ordered pairs shows that the initial volume at t = 0 is 6 gal.
