Question

Paige is filling a 3.5-L bucket at a rate of 0.25 L per minute. What is the

domain of the function that represents the volume of water in the bucket
after x minutes if the bucket was empty when Paige arrived? *

Answer 1

• [0, 14] or 0 ≤ x ≤ 14

Explanation:

The function would be:

• y = 0.25x, where y-volume of water in the bucket after x minutes

The domain is x and the range is y

The bucket will be full after 3.5/0.25 = 14 minutes

The set of possible values of x is:

• [0, 14] or 0 ≤ x ≤ 14
