The function, f(t), represents the distance from sea level, in meters, of a submarine after t minutes. select the appropriate domain for f(t). a. the set of all real numbers b. the set of all integers greater than or equal to zero c. the set of all real numbers greater than or equal to zero d. the set of all integers

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

Lol idk ask google. ejie
