question: Below is the graph of a trigonometric function. It intersects its midline at $\left(-\frac{1}{2} \pi, 3.3\right)$, and it has a maximum point at $(-2 \pi, 9.8)$. What is the amplitude of the function?
  
query_wo: Please directly answer the question and provide the final value, e.g., 1, 2.5, 300.
