Question

Which statement correctly describes the order of applying functions in \(g\circ f\)?

Options

• Apply neither function until the final step.

• First apply \(f\), then apply \(g\).

• First apply \(g\), then apply \(f\).

• Apply \(f\) and \(g\) simultaneously.

Answer 1

By definition, \((g\circ f)(x)=g(f(x))\). The input first passes through \(f\), and the resulting value then passes through \(g\).
