Question

The function, f(t), represents the distance from sea level, in meters, of a submarine after t minutes.

Answer 1

Answer:

The answer to this is c.

Answer 2

The domain for f(t) is all of the numbers t for which f(t) is defined. 

In other words, its all of the numbers that t minutes can be and still make sense in the function. 

f(t) is distance from sea level as a function of time. It does not make sense to have negative time, so t must be 0 or a positive number. t does not necessarily have to be an integer (a whole number), since you can have time values like half a minute. 

Answer is C. the set of all real numbers greater than or equal to zero
