On which of the following intervals is the function f(x) = 4 cos(2x − π) decreasing? x = pi over 2 to x = π x = 0 to x = pi over 2 x = pi over 2 to x = 3 pi over 2 x = π to x = 3 pi over 2

Option (A) is correct.

Step-by-step explanation: The given function is

We are to select the interval in which the above function is decreasing.

For the interval

So, f(x) is decreasing in this interval.

For the interval ,

So, f(x) isnot decreasing in this interval.

For the interval

So, f(x) is not decreasing in this interval.

For the interval

So, f(x) is not decreasing.

Thus, (A) is the correct option.
