    Equation of axis of a periodic function!

    I am confused on how to find it. Is it the amplitude of the periodic function or what?

    For instance i have a periodic function that is 6m between two points so amplitude = 3 and does that mean the equation of axis is y=3 ?

    any help is appreciated! and thanks in advance!

    I would imagine the axis of a periodic function (never heard it called this before) is the same as the midline ... y = 4 in the case you provided.

    Re: Equation of axis of a periodic function!

    how far is 3 from 7?

    how far is 3 from 1?

    are they equal?
