A periodic function has a maximum value of 2.5 and a minimum value of −3.5 . What is the midline of its graph?(1 point) y=
The midline of a periodic function is the horizontal line that passes through the average of its maximum and minimum values.
The average of 2.5 and -3.5 is (-3.5 + 2.5) / 2 = -1
Therefore, the midline of the graph is y = -1.
