identify the horizontal middle of a sample period for the function: f(t) = 4sec(3t - 6x)
a: x = 5 pi / 2
b: x = pi
c: x = 3 + pi
d: x = 4 pi / 3

answer: add the !

step-by-step explanation: then we will answer

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
