Question

What are the amplitude, period, and midline of a function?

Answer 1

The midline is a horizontal axis that is used as the reference line about which the graph of a periodic function oscillates.

More About MidlineThe equation of the midline of periodic function is the average of the maximum and minimum values of the functionExamples of MidlineFigure-1 shows y = sin x and Figure-2 shows y = sin x + 1. The second curve is the first curve shifted vertically up by one unit.
The midline of y = sin x is the x-axis and the midline of y = sin x + 1 is the line y = 1.

Answer 2

Answer:

Some functions repeat forever (sine and cosine) and those functions are known as periodic functions.

The period goes from from any point to the next matching point or one peak to the next peak.

The mid line or center line is a horizontal axis about which the graph of a periodic function oscillates.

The amplitude is the height from the mid line to the peak .
