Thank you We sneak in and here's your shmoop du

00:05

jour which equation is expressed in the following graph and

00:09

here your options pause warning thing part Don't worry you're

00:13

not seeing things The coast line graph really is lined

00:17

up incorrectly with the x axis values but what does

00:21

this mean Well the graph was shifted a bit to

00:24

the right or left which means that there is an

00:27

addition or subtraction to the x in the parentheses of

00:30

the co sign function which is expressed in options a

00:33

envy But now we have to just figure out if

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
