Simonne has been following the stock ratings of carter's pork bellies. she has noticed that the pattern can be modeled by a cosine function. during her observations, she has found the stock to have a maximum of x = 6, minimum of x = −2, and period of π. which of the following cosine functions could model simonne's stock rating?
f(x) = 4 cos 2x − 4
f(x) = 6 cos pi over 2x + 2
f(x) = 6 cos pi over 2x − 4
f(x) = 4 cos 2x + 2
