Question

The table provides various values, including select minimums and maximums, of a particular cosine function f (x).What is the period of the function that contains these points?

Answer 1

Given the values incorporated in the table, we have the following reasoning :

At the points (-π/2, 4) and (π/2, 4) we have maximum values of the function, then, the period can be calculated as follows:

π/2 - (-π/2) = π

So the period in this case for the cosine function described is π.
