Question

Below is the graph of trigonometric function. It has a maximum point at (1.5,3.2) and it has a minimum point at (4.75,-1.6). What is the amplitude of the function

Answer 1

2.4

Explanation:

take the two y coordinates for the min and max and add their absolute values then divide by 2

|-1.6| + |3.2| = 4.8/2 = 2.4
