Question

Function g(x) is shown below:
g(x) = 2 sin(2x - π) + 4
Find the minimum value.
Can someone help me?

Answer 1

what is the amplitude of the function?

Answer 2

2

Answer 3

2 is amplitude of 2 sin(2x -pi), not the given one. But anyway, we can derive g(x) from it.

Answer 4

Now, I let h(x) = 2sin(2x-pi) , so we have amplitude of h(x) is 2, ok?

Answer 5

ok

Answer 6

That is, the minimum of h(x) is -2, ok?
