Answer
horizontal shift
cosine graph, find a ___maximum______ point and use the _x_-coordinate
Reflected cosine graph, find a ____minimum_____ point and use the _x_-coordinate
Work Step by Step
To find the horizontal shift for a cosine graph, find a ___$maximum$______ point and use the _$x$_-coordinate of that point. To find the horizontal shift for a reflected cosine graph, find a ____$minimum$_____ point and use the _$x$_-coordinate of that point.
Because a cosine cycle begins at its maximum value, the horizontal shift will be the corresponding x-coordinate of this point.
