A baker records the internal temperature of a pie that has been left to cool on a counter. The room temperature is 21°C. An equation that models this situation is T(t)= 70(0.5)t/9 + 21 where T is the temperature in degrees Celsius and t is the time in minutes. d) Determine the domain of the function in the context of the problem. e) Determine the range of the function in the context of the problem.
