an object oscillates 4 feet from its minimum height to its maximum height. the object is back at the maximum height every 3 seconds. which cosine function may be used to model the height of the object?

a

y=4cos2π3t

b

y=2cos3πt

c

y=2cos2π3t

d

y=2cosπ3t

  C  y=2cos(2π/3t)

Step-by-step explanation:

The amplitude of the function will be half the difference between the minimum and maximum: 4/2 = 2.

The multiplier of t in the function will be 2π/period = 2π/3.

Comment on the answer choices

The answer choices need to be "interpreted" in order to choose one. As written, none is correct.
