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

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

Step-by-step explanation:

For any functions f and g on x , the sum of functions is equivalent to

OR

Thus, for x=4 we have

The expression is equivalent to

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.
