2: Consider the shift-invarient system f with time-varying input x(t) and time-varying response y(t).

y(t) = f [x(t)]

Sinewaves are the eigenfunctions of a shift-invarient linear system. Which of the following mathematical statements express this fact correctly?

f [\alpha \;sin (2\pi\omega t\; +\; \psi)] = \beta\;sin (2\pi\omega t\; + \phi)

f [alpha sin (2 pi omega t + psi)] = beta sin (2 pi omega t + phi)

f [alpha sin (2 pi omega t + psi)] = alpha sin (2 pi omega t + phi)

f [alpha sin (2 pi omega t + psi)] = sin (2 pi alpha omega t + phi)

f [alpha sin (2 pi omega t + psi)] = beta sin (2 pi omega t + psi)

f [alpha sin (2 pi omega t + psi)] = alpha sin (2 pi omega t + psi)
