find the amplitude of the sinusoidal function.\nsimplify any fractions.\namplitude =

Answer:

1

Explanation:

Step1: Recall amplitude formula

Amplitude $A=\frac{\text{max}-\text{min}}{2}$.

Step2: Identify max and min

From the graph, $\text{max}=- 4$, $\text{min}=-6$.

Step3: Calculate amplitude

$A=\frac{-4 - (-6)}{2}=\frac{-4 + 6}{2}=\frac{2}{2}=1$.
