Answer:[tex]f(4)+g(4)[/tex]
Step-by-step explanation:
For any functions f and g on x , the sum of functions [tex](f+g)(x)[/tex] is equivalent to [tex]f(x)+g(x)[/tex]
OR
[tex](f+g)(x)=f(x)+g(x)[/tex]
Thus, for x=4 we have
[tex](f+g)(4)=f(4)+g(4)[/tex]
The expression [tex]f(4)+g(4)[/tex] is equivalent to [tex](f+g)(4)[/tex]
f(4) and g(4) means that we should find the value of our function when x equals 4.
(f+g)(4) means we should find the value of our function as sum, when x equals 4.
