I really need help with this ^-^

The graph of a function is shown in the picture and the amplitude will be 6
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 = 6
Thus, the graph of a function is shown in the picture and the amplitude will be 6
