Answer:

  frequency = 1/(2π)

Step-by-step explanation:

The frequency of the function is found by comparing the argument of the cosine function to (2πfx), where f is the freuqency.

  2πfx = x . . . . the argument of the cosine is x in f(x)=2cos(x) -4

  2πf = 1 . . . . . . divide by x

  f = 1/(2π) . . . . . the frequency of the function f(x)
