Question

Mrs. Palmer is filling a bucket with water from a hose. The amount of water in the bucket after x seconds is given by the function f(x). The amount of water is measured in liters.
What does f(4)<2 tell you?

Answer 1

Since x is seconds and f(x) is liters, f(4) < 2 means that after 4 seconds the bucket contains less than 2 liters of water. It does not say how much less, nor what happens at other times.
