Final answer:
The domain of a graph modeling the temperature change of water on a stove represents all the possible time values during which the temperature was measured. Without the graph, we infer that it starts at zero minutes and ends when the chef stops heating or when recording stops.
Step-by-step explanation:
The question is asking us to determine the domain of a graph that models the temperature change of water over time as it is heated on a stove. The domain in a graph represents all the possible inputs, or in this context, the time in minutes during which the changes in temperature are observed. Given the context, the domain would typically be from when the chef starts heating the water (time = 0 minutes) to when the chef stops, or when the recording stops.
To find the domain, we look at the graph and note the minimum and maximum time values recorded during the observation of the temperature change. The temperature changes from the moment the heating starts (minimum time value) until the process ends or stops being measured (maximum time value). Therefore, without the explicit graph, we cannot determine the exact domain, but we can infer it to likely be all the minutes during which the temperature was being recorded.
