- 00:36
it's plus two or minus two a plus two would
- 00:40
mean a shift to the left while a minus two
- 00:42
would mean a shift to the right If we were
- 00:44
to draw a normal co sign graph on the same
- 00:46
set of axes it would be a bit to the
- 00:48
right of the one shown The graph here was shifted
- 00:51
to the left yielding result of co sign of the
- 00:54
quantity x plus two This is represented in choice eh 00:00:58.13 --> [endTime] which turns out to be our answer
