An aquarium is being filled at a rate of 2.5 inches per second. The equation y=2.5x is used to determine the height of the water after x seconds. Find the domain and range of the situation if it takes 60 seconds to fill the aquarium

Answer:

  • domain: 0 ≤ x ≤ 60
  • range: 0 ≤ y ≤ 150

Step-by-step explanation:

The reasonable domain of the function is the time range over which it is applicable: 0 to 60 seconds. The function will not give appropriate answers after the time that the aquarium is full.

The reasonable range of the function is the set of values corresponding to the reasonable domain: 0 to 2.5×60 = 150 (inches).
