Do I shift right two units? C.

kenljw · Answer

The average, mean, value of a cos or sin is zero, therefore any constant added would be the horizontal displacement.

sorry that's vertical

I think it be D but im not sure at all...

kenljw · Answer

a cos or sin occur when their argument, that in parenthesis, in zero, therefore x = 2 which if you draw it is a shift to the right.

agent0smith · Answer

cos(x-2): the -2 means a shift to the right, since as @KenLJW you want to set the part inside brackets to zero ( x-2=0 so x=2 )
