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)?

all positive real numbers

[0, 1200]

all negative real numbers

[−22, 0]

B. [0,1200]

Step-by-step explanation:

We are given that,

The function f(x) represents the number of feet below the surface of water a dive is at 'x' seconds.

It is given that,

At 14 sec, the diver has reached the maximum distance of 22 feet below the surface.

Further, he stayed there for another 20 minutes = 1200 seconds.

So, the time limit for which the diver was inside the water is 0 to 1200 seconds.

Thus, the practical limit for the domain is [0,1200].

Hence, option B is correct.

[ 0, 1200 ]

This is the correct answer because I just took the test! Good luck!

the correct is answer is a 9-sided polygon!

pakistan's principal natural resources are arable land and water. about 25% of pakistan's agriculture accounts for about 21% [1] of gdp and employs about 43% of the labour force. in pakistan, the most agricultural province is punjab where wheat and cotton are the most grown.
