For the image with root cos x, all the points on the image with root cos (2x + π / 4) are needed

There are two ways to change x into 2x + π / 4. First, X --- > 2x --- > 2 (x + π / 8), reduce the horizontal axis by two times and then shift π / 8 to the left. Second, X --- > x + π / 4 --- > 2x + π / 4, shift π / 4 to the left and then reduce it by two times. You should be very proficient in y-axis. Think about it carefully, I hope you can raise one against three
