Question

what is the amplitude of the graph below?
options: 0.25, 9, 2, 0

Explanation:

Step1: Recall amplitude definition

Amplitude = $\frac{\text{Max } y - \text{Min } y}{2}$

Step2: Identify max/min y-values

Max $y=2$, Min $y=-2$

Step3: Calculate amplitude

$\frac{2 - (-2)}{2} = \frac{4}{2} = 2$

Answer:

2 (Option: 2)
