Question

What is the amplitude of the sinusoidal function? Enter your answer in the box.

Answer 1

Answer:

3

Step-by-step explanation:

The magnitude is found by taking the maximum to the minimum

max = 3

minimum = -3

Magnitude = 3--3 = 3+3 =6

The amplitude is 1/2 the magnitude

Amplitude = 1/2 *6 =3

Answer 2

Answer:

3

Step-by-step explanation:

We have been given graph of a function. We are asked to find the amplitude of our given function.

We know that the Amplitude is the height from the center line to the peak of the function.

We can see that mid-line of our given function is $y=0$. The amplitude of our given function will be maximum height of our function from mid-line.

We can see that the height of function from mid-line is 3 units, therefore, the amplitude of our given function is 3.
