Question

Identify the horizontal middle of a sample period for the function: f (t) = 4sec(3t − 6π). I got the answer x=4pi/3

Answer 1

Do you have answer choices for this question? There are infinite answers to this question.

Answer 2

the answer choices are x=4pi/3, x=5pi/2, x=pi, and x=3+pi

Answer 3

x = pi and x = 4pi/3 both work.

Answer 4

yes but there is only 1 choice

Answer 5

y = f(x) = a cos ( k( x - b) ) + c
Where :
"a" is the amplitude
"b" is the horizontal shift
The horizontal shift here would be \(2\pi\)
So I'm guessing what they mean by horizontal middle is half of the horizontal shift \(\pi\).
