The function ​f(x)​ is the number of feet below the surface of the water a diver is at x seconds. After 14 s, the diver reached the maximum distance of 22 ft below the surface of the water. The diver stayed in the water for 20 minutes.

 

What is the practical domain for the function f(x)?

 

Answer choices: 

  • all positive real numbers
  •   [0, 1200]
  •   [−22, 0]
  • all negative real numbers

It is a bit confusing but x is the domain and x is in second

He is in the water for 20 minutes = 1200 second

 

so a sensible domain would be [0 , 1200]
