What is the frequency of the function f(x)? f(x)=3cos(πx)−2 express the answer in fraction form.

The frequency of given function is

Step-by-step explanation:

Given : Function -

To find : The frequency of the function

Solution :

General form of cosine function is

Where A is Amplitude

C is Mid line

And the frequency is given by

, F is frequency and P is period

Now, we find period,

Comparing the given function with general form of cosine we get,

Period -

and we know,

Equating the terms,

Period=2

Frequency is

Therefore, The frequency of given function is

step-by-step explanation: yes
