Question

Write a cosine function that has an amplitude of 4, a midline of 2 and a period of1

Answer 1

Answer:

see below

Step-by-step explanation:

start with cos (x)

  amplitude 4

      4 cos x

      midline 2

          4 cos (x )    + 2

        period of 1   :      2 pi / 1 = 2 pi   

                multiply x   by 2pi

                        4 cos ( 2 pi x)  + 2
