Which Expression is Equivalent to (f + g)(4)?

a) f(4) + g(4)    b) f(x) + g(4)   c) f(4 + g(4))    d) 4(f(x) + g(x))

We will be using the concept of functions to solve this.

Answer: The Expression (f + g)(4) is equal to f(4) + g(4).

Let's solve this step by step.

Explanation:

Given that, (f + g)(4)

We know from the definition of function that (f + g) (x) = f(x) + g(x)

⇒(f + g) (4) = f(4) + g(4)

Thus, the expression (f + g)(4) is equal to f(4) + g(4).
