Part I
- The domain of the graph is represented by 0 ≤ x ≤ 12
- In terms of the problem the domain means the time in hours taken to notice change in temperature in degrees Celsius.
Part II
- The range of the graph is represented by -2 ≤ x ≤ 4
- In terms of the problem the range means the temperature in degrees Celsius noted during the time spent, the time is in hours
Part III
- The function is decreasing from 0 to 3 hours, this is the point in the x axis that is mathematically represented as 0 ≤ x ≤ 3.
- This decreasing interval means that it is getting cold, since the temperature is dropping and temperature drop implies getting cold.
What temperature?
This a term that represents the amount of how hot or cold a substance is the unit used to measure temperature as regards the question is degrees Celsius.
The range of the graph is temperature while the domain is the time
