mine the amplitude of the following graph.

Explanation:

Step1: Recall amplitude formula

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

Step2: Identify max and min values

From the graph, $\text{Max} = 3$ and $\text{Min}=- 3$.

Step3: Calculate amplitude

$A=\frac{3 - (-3)}{2}=\frac{3 + 3}{2}=\frac{6}{2}=3$.

Answer:

$3$
