Given:

Given a table of values of a cosine function.

Required: Period of the function

Step-by-step explanation:

The maximum of the cosine function occurs at the points


x=-2\pi\text{ and }x=2\pi

The period of the function is the modulus of the difference of the consecutive values at which the function attains maximum/minimum.


\begin{gathered} \text{ Period=}|-2\pi-2\pi| \\ =|-4\pi| \\ =4\pi \end{gathered}

Final Answer: The period of the given cosine function f(x) is


4\pi
