Answer:
Step-by-step explanation:
This has a very brief answer when you know what it means.
f(x) + g(x) = abs(x) + 9 - 6
f(x) + g(x) = abs(x) + 3
Answer:
f + g)(x) = |x| + 3
Step-by-step explanation:
Add the two functions together:
f(x) = |x| + 9
+g(x) = - 6
------------------------
f(x) + g(x) = |x| + 9 - 6
= |x| + 3
The label f(x) + g(x) can be rewritten as (f + g)(x).
Thus, f + g)(x) = |x| + 3
