Answer to Problem 32AYU
a. The domain of
Explanation of Solution
Given:
;
Calculation:
The domain of and the domain of are the set of all real numbers.
Because the domains of both and are the set of all real numbers, the domain of is the set of all real numbers.
We know the composite function of and is defined as
