Question

Find the amplitude of the sine curve shown below.

Answer 1

Hello,

your curve is y=4sin(x)
amplitude=4

Answer 2

4.

Explanation:

We have been given an image of sine function and we are asked to find the amplitude of our given function.

Since we know that amplitude of an function represents half the distance between the maximum and minimum values of the function.

We can see that maximum value of our given function is 4 and the minimum value of our given function is -4.

Since 4 and -4 is 4 above and below the mid-line respectively, therefore, amplitude of our given function is 4.
