Raj's bathtub is clogged and is draining at a rate of 1.5 gallons of water per minute. The table shows that the amount of water remaining in the bathtub, y, is a function of the time in minutes, x, that it has been draining. What is the range of this function? all real numbers such that y ≤ 40 all real numbers such that y ≥ 0 all real numbers such that 0 ≤ y ≤ 40 all real numbers such that 37.75 ≤ y

Im taking a unit test on edge nuity and C is the correct answer. Happy National Even Day

Mindy · Answer 2

The correct answer is all real numbers such that 0≤y≤40.

Explanation:

The least amount of water possible in the tub is 0. There can be no number less than that in the range. This eliminates the first and last choices for answers, since they have no lower bound. We cannot say that it is all real numbers such that y≥0, because that would be an endless amount of water in the tub. This leaves all real numbers between 0 and 40.
