The final range of the function is
Domain of the total function is
Explanation of Solution
Given information:
Given function,
Calculation:
Graph:
Given the
Therefore the domain of the first function is
For the second equation the
Therefore the domain of the second function is
So these two inequalities
Therefore, the combined final domain of the total function is
The range of the first function
Therefore, the range of the first function is
For the second equation
When
Therefore, the range of the second function starts from 2 and raises above 2.
Therefore the range of the second function is
So the final range of the function is
