Answer:Frequency =Step-by-step explanation:We are given the following function and we are to find its frequency:

We know that the standard form of cosine function is

where is the amplitude, while is the mid line.

Frequency is given by:

where is frequency and is the period.

Finding period by comparing the given function:

Substituting B to get:

So, Period = 2.

Since frequency is , therefore

Frequency =
