Use the function below:

trig graph with points at 0, 2 and pi over 2, 0 and pi, 2 and 3 pi over 2, 4 and 2 pi, 2
What are the amplitude and midline? (5 points)


Amplitude: 1; midline: y = 1

Amplitude: 1; midline: y = 2

Amplitude: 2; midline: y = 1

Amplitude: 2; midline: y = 2


I'm going to have two more questions posted, so if you know this can you check out the other one's

Answer :

The given data is
x:  0     π/2    π    (3π)/2   2π
y:  2     0       2    4           2

The function that models the data is (see the graph shoen below)
[tex]y=2cos(x+ \frac{ \pi }{2})+2 [/tex]

The amplitude is 2.
The midline is y = 2
The phase is -π/2.
The period is 2π.

Answer:
Amplitude: 2; Midline: y = 2
