Which of the following is the graph of y=cos[2(x+pi)]
Fittoniya [83]

Answer:

<em>*The graph is attached below.</em>

Step-by-step explanation:

The given function is,

y=\cos 2(x+\pi)

We know that, in the function

y=a\cdot \cos b(x+c)+d

  1. period is \dfrac{2\pi}{b},
  2. horizontal shift or phase shift is c,
  3. amplitude is a,
  4. vertical shift is d.

Hence, in the given function the period is \dfrac{2\pi}{2}=\pi, horizontal shift is \pi towards left (as it is +\pi), amplitude is 1 and vertical shift is 0.
