Question

Which expression is equivalent to (f + g)(4)?

Answer 1

(f + g)(x) = f(x) + g(x) therefore (f + g)(4) = f(4) + g(4)

Answer 2

Answer:$f(4)+g(4)$

Step-by-step explanation:

For any functions f and g on x , the sum of functions $(f+g)(x)$ is equivalent to $f(x)+g(x)$

OR

$(f+g)(x)=f(x)+g(x)$

Thus, for x=4 we have

$(f+g)(4)=f(4)+g(4)$

The expression $f(4)+g(4)$ is equivalent to $(f+g)(4)$

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.
