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.

$x$	$y$
0	40
0.5	39.25
1	38.5
1.5	37.75

What is the range of this function?

Aall real numbers such that $y \leq 40$

Ball real numbers such that $y \geq 0$

Call real numbers such that $0 \leq y \leq 40$

Dall real numbers such that $37.75 \leq y \leq 40$
