Question

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))

Answer 1

To evaluate the expression \((f + g)(4)\), we need to understand that \((f + g)(x)\) is defined as \(f(x) + g(x)\). Therefore,

\[
(f + g)(4) = f(4) + g(4).
\]

So the expression that is equivalent to \((f + g)(4)\) is:

\[
\boxed{f(4) + g(4)}.
