Question

What is the amplitude of y=4 sin 1/3 x

Answer 1

4

Explanation:

The amplitude of the sin graph is 4. Sin graphs are written as
`y=A sin(B(x-D))+C` where A is the amplitude. In the equation above 4 is multiplied in front of sin, which shows it is the amplitude. Since 4 is the amplitude the graph will have a range of [-4,4].
