To find: To find the domain for given situation, write an inequality and to find the least time spend on the phone per week and to find the most time spend on the phone per week.
The domain of the situation is
The inequality for the graph given is
The least time spent on the phone per week is
The most time spent on the phone per week is
Given information:
The graph at the right angle relates the number of hours spend on the phone to the number of hours spend studying per week. Describe the domain and write an inequality for the graph. What is the least amount of time spent on the phone per week and what is the most amount of time spent on the phone per week.
Calculation:
From the graph
Let
The domain of the situation from the graph is:
When
Therefore, the boundary line of the graph is
Since the boundary line is solid and the region shaded is below the boundary line, the inequality will be:
The least time spent on the phone per week is when
The least time spent on the phone per week is
The most time spent on the phone per week is
To find: The least time spend on the studying per week and to find the most time spend on the studying per week.
The least time spent on the studying per week is
The most time spent on the studying per week is
Given information:
The graph at the right angle relates the number of hours spend on the phone to the number of hours spend studying per week.
Calculation:
The least time spent on studying per week is when
The least time spent on the phone per week is
The most time spent on the phone per week is
To find: The greatest amount of time spent either on the phone or studying per week.
The greatest amount of time spent either on the phone or studying per week is
Given information:
The graph at the right angle relates the number of hours spend on the phone to the number of hours spend studying per week.
Calculation:
From the graph, the greatest amount of time spent on the phone per week is
Therefore, the greatest amount of time spent either on the phone or studying per week is
