Answer:
-3
Explanation:
A composite function is formed when one function is applied to the result of another function. In this case, (f + g)(x) is formed by adding the function g(x) from the function f(x).
Therefore, to find (f + g)(1), we need to add function g(x) to function f(x) and then evaluate the result at x = 1.
Given functions:


Calculate f(x) - g(x):

Now, substitute x = 1 into the expression:

Therefore:
