Mathematics: Which of the following would best represent a cosine function with an amplitude of 3, a period of pi over 2, and a midline at y = −4? f(x) = −4 cos 4x + 3 f(x) = 3 cos(x − pi over 2) − 4 f(x) = 4 cos(x − pi over 2) + 3 f(x) = 3 cos 4x − 4

The second choice is the correct answer I believe. Mid-line is always at the end so the only options you would have is the second choice and the last but you cant have your period equal to zero.

Step-by-step explanation:

(5/3)y-8 = (7/3)y-16

(5/3)y- (7/3)y = 8 -16

(-2/3) y = -8

y = 3*8/2

y=24/2

y=12
