If a fundamental frequency is f, which of these would be considered a harmonic component?

Explanation:
Harmonic components are frequencies that are integer multiples of the fundamental. If the fundamental is f, the harmonic frequencies include 2f, 3f, 4f, and so on. So 2f is a harmonic because it is exactly twice the fundamental. The others don’t fit: f/2 is a subharmonic (lower than the fundamental), and f^2 or f^3 aren’t multiples of f, so they aren’t harmonics in the usual sense.
