Answer:
Domain= time
Range= temperature
Step-by-step explanation:
Initially hot water cools down over time.
This can be expressed as a function of a temperature by a time. It takes 25 minutes for water to cooled down from 100°F to body temperature.
For any value of the time (from zero to 25 minutes), the temperature has certain value (from 100°F to body temperature). As time value increases, temperature value decreases accordingly.
In this example, time is the domain and temperature is the range.
