The cosine function that can model this real-world scenario is:
f(x) = -106cos (4x) + 106. See how the same is derived below. The full question is also attached.
What is a Cosine Function?
A Cosine Function is a periodic function that is denoted as Cos x. See the attached image.
The above function is derived as follows:
T = 2π/4 = π/2 = 2π/ω
Therefore, ω = 2π/π/2 = 4
This means f(x)= -106 cos (4x) + 106
