### Transformation of the Cosine FunctionConsider the following graph of the function \( f(x) \) which is a transformation of the cosine function. Find a formula for \( f(x) \).(You may assume that the period and any phase shift here are some nice multiple of π. For example, \( \frac{\pi}{2} \) or π or 2π, etc. The period or phase shift will **not** be something like 3 or 6.)\[ f(x) = \]#### Description of Graph:The graph provided is a sinusoidal wave, which resembles a cosine function but has undergone transformations such as scaling and horizontal shifts. The x-axis is divided into \(\pi\) units, and the wave completes its period exactly at a multiple of \(\pi\).The crucial points to note are:- The peaks and troughs of the wave.- The period of the wave, which can be derived from the distance between consecutive peaks or troughs.- The amplitude (the maximum and minimum values) should be considered to identify any vertical scaling.From visual inspection:- The period appears to be \( \pi \).- The amplitude (the vertical distance from the x-axis to the peak) seems to be 2.- There is no horizontal shift observed directly in the snapshot.Using these observations, we can construct a function \( f(x) \):\[ f(x) = 2 \cos(2x) \]Here, the cosine function is transformed with an amplitude of 2 (vertical scaling) and a period adjustment to \( \pi \) (indicated by the factor 2 inside the cosine function).
