Respuesta :

The  amplitude of a sine curve is the largest distance between the base line and the highest peak.

The baseline is y = 0 in this case, and the highest point reached is 4, so the amplitude is 4.
ANSWER

The amplitude is
[tex]4[/tex] units.

EXPLANATION

The [tex]<b>amplitude[/tex] is the measure of the the height from the center line to the peak or the trough of the given sine graph.

[tex] amplitude = |4 - 0| = 4[/tex]

Or

We can also measure from the lowest height up to the highest height and divide by two to get the amplitude.

[tex] amplitude = \frac{ |4 - - 4| }{2} [/tex]

[tex] amplitude = \frac{ 8 }{2} = 4[/tex]
