Alice’s freezer can be set to a range of temperatures from -6degrees to -1degrees Celsius when the temperature is -1 Celsius it
tasked water 4 hours to freeze, which is the longest time the shortest time is 2 hours, when the temperature is set to -6 degrees Celsius. T(t) models the time (in hours) it takes water to freeze at a temperature of t degrees celsius. Which number type is more appropriate for the domain of T? Integers or Real numbers?

Answer:
B. ; Integers.
Step-by-step explanation:
We have been given that models the time (in hours) it takes water to freeze at a temperature of t degrees Celsius.
We know that domain of a function is values of independent variable for which the function s defined.
We can see that temperature in degrees is independent variable for the given function, so domain of function would be values of temperature for which function is defined.
Since the upper limit of temperature is degrees and lower limit is
degrees. so the domain of temperature will less than or equal to
and greater than or equal to -6 that is
and option B is the correct choice.
The temperature in degrees Celsius is domain of function, so the domain of function would be integers.
Therefore, integer numbers is more appropriate domain of T.
