Answer:
Correct Answer: D. the midline is 2
Explanation:
The maximum is the largest value of the function: 5. (not 2)
The minimum is the smallest value of the function: -1. (not -2)
The amplitude is half the difference of the minimum and maximum: (5-(-1))/2 = 3. (not 2)
The midline is the average of the minimum and maximum: (5-1)/2 = 2.
