Question

what is the amplitude of the graph below?
options: 0, 1, 0.5, 3

Explanation:

Step1: Recall amplitude definition

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

Step2: Identify max/min y-values

Max $y=1$, Min $y=0$

Step3: Calculate amplitude

$\frac{1 - 0}{2} = 0.5$

Answer:

0.5
