Consider the following graph on the interval -225degree

Solution

The amplitude of a wave is basically a measure of its height. Because that height is constantly changing, amplitude is defined as the farthest distance the wave gets from its center.

from the graph the amplitude =3

The period of a function is the horizontal length of one complete cycle.

period= 90+90=180

equation:y=x
