Final answer:
The concept of domain and range is best illustrated by the recording of a city's temperature hourly over a month, which relates to changes over time and temperature fluctuation visually represented on a time series graph.
Step-by-step explanation:
In real-life scenarios, the concept of domain and range can be readily understood through example B) A city's temperature recorded hourly over a month. The domain in this case would be the specific hours or times at which the temperature is recorded, and the range would be the actual temperatures that were recorded during those times. It's a clear example of how data can be graphed and analyzed to understand trends and patterns, similar to constructing a time series graph.
For instance, representing the temperatures recorded at noon every day for a month on a graph, where the x-axis would represent the days (time) and the y-axis the temperatures, helps visualize the fluctuations in temperature over time. This time series graph would use chronological order to highlight how variables change over time. Such visualization is critical for identifying trends, such as warming or cooling periods, within that month.
