Now we apply to this result:
Thus, .

6. Determine .

To find , we substitute into :
Now substitute into :
Expanding :
So:
Thus, .

7. Determine the domain of .

The function is defined for all real numbers. Since is also a polynomial, it is defined for all real numbers as well. Therefore, the domain of is all real numbers:

8. Determine .

To find , we substitute into :
Now, substitute into :
This expands to:
Thus, .

9. Determine the domain of .

The function is defined for all real numbers except . Hence, the output of will also exclude 0. Therefore, since takes all values except for 0 should be considered:
