Question

The table provides various values including all minimum and maximum of a cosine function f(x) on the interval [0, pi] What is the period of the function

Answer 1

Remember that

The Period goes from one peak to the next (or from any point to the next matching point)

so

Looking at the given table

x=0 -----------> f(x)=1

x=pi -----------> f(x)=1

therefore

Period=pi

the answer is pi
