What is the frequency of the function f(x)? f(x)=1/4 cos(2x)+5?

We have to find the frequency of given function  f(x)=1/4 cos(2x)+5 for this we will adopt the general procedure of first finding the period and then use the general relation frequency=1/period and find the frequency.

In the given function f(x)=1/4 cos(2x)+5 only the constant 2 which will multiply with x effects the period
As we know that 2π is the period of cosx then the period of cos(2x) is
 2x=2π
x=π
So, the period of cos(2x) is π
Now the frequency is F=1/π

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.

Dis the correct answer
