Answer to Problem 68AYU
The value of
Domain of
Explanation of Solution
Given information:
The functions are
Formula Used:
Let f and g be two functions.
Use the sum formula,
For a composite function
If domain is not specified for a function, one should consider the set of largest real number where the function is defined all over.
Calculation:
The functions are
Use the sum formula,
Substitute
Hence, the value of
As domain of
So, domain of
