Question

Check my answer please!!! Horizontal middle line? Graph attached!

Answer 1

Only answer that makes sense is D

Answer 2

does it tell you where the sample period starts? and why do you think it's x = 0?

Answer 3

@jim_thompson5910 It doesn't say where the sample period starts, I think it's X=0 because the graph looks like this when I split it there

Answer 4

well I was thinking x = pi because 2pi is the period

if you started at x = 0, then the midpoint of x = 0 and x = 2pi is x = pi

Answer 5

this question seems a bit vague and that it's missing something

Answer 6

@jim_thompson5910 x=pi isnt an option :/

Answer 7

something looks missing yeah but I need to pick something based on what's available...what seems the closest? It still looks like it's D

Answer 8

yeah unfortunately x = pi isn't an option. So I guess x = 0 is probably the next best thing.

Answer 9

I guess if you look at it like this
