Answer:
Composition:
Domain = { }
Step-by-step explanation:
Given
The requested composition becomes:
Then the Domain consists of all Real x-values for which the function is defined. In this case, the function is defined for all x-values for which the square root is defined, that is all x values for which:
(so the square root is defined in the Real number system)
This means
The Domain is then all the Real x-values such that
