Below is the graph of a trigonometric function. It has a minimum point at (-5.4, 1.25) and a maximumpoint at (7.4, 6.75). What is the amplitude

To determine the amplitude we need to see where is the middle line of the function, the middle line passes through the middle value of the y components of the maximum and minimum. Then the middle line passes through;


(1.25+6.75)/(2)=4

Now, the amplitude is the vertical distance between the maximum and the middle value, then in this case we have:


6.75-4=2.75

Therefore the amplitude is 2.75
