Harold wrote this equation to model the level of water in a pool over time. The variable x represents time in hours. f⁡(x)=3,500−225⁢x Which statements about the situation are true? Choose three correct answers.

At 4 hours, the model gives f(4) = 3,500 − 225(4) = 2,600, so the water is 2,600 units high (C). At time 0, the level is f(0) = 3,500, making 3,500 units the initial level (E). The negative coefficient, −225, means the water level falls by 225 units each hour (F).
