Question

What is the amplitude of the sinusoidal function?

Answer 1

answer is 5

Explanation:

max - min divided by 2

6 - -4 = 10

10 divided by 2 = 5

Answer 2

The amplitude of a sinusoidal wave is half the distance between the y-coordinates of minimum and maximum points. Or, if you prefer, the distance between the midpoint and the minimum/maximum.

In this case, you can see that when the maximum is reached we have
`y=6`, and similarly for the minimum,
`y=-4`.

Half the distance between max and min is thus

`A=(6-(-4))/(2) = (10)/(2) = 5`
