Part A:
Given:
Newspapers circulated in year 2004,
Newspapers circulated in year 2014,
Let the time start at the year 2004. So,
For the year 2014,
Therefore, linear relationship between newspapers circulated and time passed since 2004 is given as:
Therefore, the equation describing the relationship is:
Part B:
For the year 2018,
Plug in 14 for in the above equation and solve for
. This gives,
Therefore, in the year 2018, the newspaper circulation will be 42.2 million.
Given:
The inequality is:
To find:
The domain and range of the given inequality.
Solution:
We have,
The related equation is:
This equation is defined if:
In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.
So, the domain of the given inequality is x>-3.
We know that,
The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.
So, the domain of the given inequality is y>1.
Therefore, the correct option is A.
