Question

Which expression is equivalent to (f g) (5)?
f (5) times g (5)
f (5) + g (5)
5 f (5)
5 g (5)

Answer 1

The expression \((f g)(5)\) refers to the composition of the functions \(f\) and \(g\) applied to the input \(5\). The process involves multiplying the outputs of both functions at that input, which can be mathematically represented as \(f(5) \cdot g(5)\).

Thus, the expression that is equivalent to \((f g)(5)\) is:

**f(5) times g(5)**
