i really need help with this

The graph of a function is shown in the picture and the amplitude will be 6What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle. We have a trigonometric function:[tex]\rm y = -6\cos\left(5x\right)-3[/tex]As we know, the range for the cosx is [-1, 1]The maximum value of function y = -6cos(5x)—3 is 3 and minimum value is -9.The amplitude = 6Thus, the graph of a function is shown in the picture and the amplitude will be 6Learn more about trigonometry here:brainly.com/question/26719838#SPJ1
