Answer:
(f+g)(x) =f(x)+g(x)
Step-by-step explanation:
(f+g)(x ) is f(x) +g(x)
that is in order to find f+g value at x ,we have two ways
(i) first we add simplify f and g by adding and then plug the value at which we need the value
(ii) we find the value of f(x) and g(x) individually and then we add the obtained values.
so here in order to find (f+g)(4)
Either we add f and g first.and then find value at x =4
or
find f(x) at x =4 and g(x) at x=4 and then we add the obtained value
