What is the amplitude of the function shown in the graph? Enter your answer in the box.

Answer: A = 2.5
Step-by-step explanation:
The highest point is 5.5. The lowest point is 0.5.
[tex]Amplitude (A) = \dfrac{high-low}{2}[/tex]
[tex]A = \dfrac{5.5-0.5}{2}[/tex]
[tex]= \dfrac{5}{2}[/tex]
[tex]= 2.5[/tex]
