Question

SOMEONE PLEASE HELP ME I DONT KNOW HOW TO DO THIS AT ALL

Answer 1

`y=2cos(4\pi x)\\`

Explanation:

Since the amplitude of the cosine function is 2, I would put the multiply it by 2. There is no phase shift

The period is 1/2, so it would be 4pi

Plug them in into y=Acos(Bx), y=2cos(4pix)
