I need help PLEASE Write a cosine function that has an amplitude of 2, a midline of 4 and a period of 4.

Step-by-step explanation:

The standardized cosine function is ;

Amplitude |A| = 2

Period

2π = 4B

Midline y = 4;  D = 4

Phase shift; since no phase shift is given; then C = 0

The cosine function:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
