Question

Using complete sentences, explain how to find the maximum value for each function
f(x) = 2cos(x)

Answer 1

The posted question and the posted diagram do not match. The diagram is about sine and the question is about cosine.

Which problem would you like to do?

Answer 2

sorry, f(x) is the first function and g(x) is the second
I'm supposed to find the maximum value of both

Answer 3

g(x) is the graph. Should've specified.

Answer 4

max. value of f(x)=2 cos x=2*1=2
Because
\[\left| \cos x \right|\le 1\]

Answer 5

ah okay
