Question

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. A 2-column table with 4 rows. The first column is labeled x with entries 0, 0. 5, 1, 2001. 5. The second column is labeled y with entries 40, 39. 25, 38. 5, 37. 75. What is the range of this function?

a. all real numbers such that y ≤ 40
b. all real numbers such that y ≥ 0
c. all real numbers such that 0 ≤ y ≤ 40
d. all real numbers such that 37. 75 ≤ y ≤ 40.

Answer 1

Draining rate is at 1.5 gallons per minute

That would be y = 1.5g / x.

From the function or the equation, here is the answer.

The range would be all real numbers such that 0 ≤ y ≤ 40.
