Harold wrote this equation to model the level of water in a pool over time. The variable x represents time in hours. f(x) = 3,50
lina2011 [118]

Answer:

The water level is falling.

The initial level of water in the pool was 3,500 units

The water was 2,600 units high after 4 hours.

Step-by-step explanation:

The given function that models the water level is

f(x)=3,500-225x

where x represents time in hours.

The function represents a straight line that has slope m=-225

Since the slope is negative, it means the water level is falling.

The initial level of water in the pool can found when we put x=0 into the function.

f(0)=3,500-225(0)


f(0)=3,500, hence the initial level is 3,500.


To determine the level of water in the pool after 14 hours, we put x=14 into the equation to get;

f(14)=3,500-225(14)

f(14)=3,500-3150


f(14)=350


To determine the water level after 4 hours we put x=4

f(4)=3,500-225(4)

f(4)=3,500-900

f(14)=2,600
