Question

Find the amplitude and the equation of the midline of the periodic function

Answer 1

Answer:

amplitude:  3; midline is y = 2

Step-by-step explanation:

Note that the range of this function is [-1, 5], values that are 6 units apart.  The amplitude is half that, or 3 units.

The midline is the horiz. line halfway between -1 and +5.:  y = 3.

These values correspond to the last (fourth) answer choice.
