Finding a Cosine Function that Models Damped Harmonic Motion

Find and graph a function of the form $y = a e^{- c t} cos (ω t)$ that models the information given.

ⓐ $a = 20, c = 0.05, p = 4$
ⓑ $a = 2, c = 1.5, f = 3$

Its source prints no answer for this problem, so there's nothing to check against.
