Question

What is the amplitude of the function below?

Answer 1

The amplitude is 2 or B.

Answer 2

ANSWER

The amplitude is

`2`


Step-by-step explanation

The amplitude is the height of the function from the centre line which is

`y = 0`

to the peak or trough of the graph, which is

`y = 2`
This means that,

`amplitude = |2 - 0| = 2`


Or

The amplitude is distance between the lowest point on the graph and the highest point on the graph divided by 2.



`amplitude = (1)/(2) |2 - - 2| = (1)/(2) * 4 = 2`
