It moves horizontally 1/2 units to the left
It moves vertically 2 units up
Step-by-step explanation:
∵ y = Acos(Bx - C) + D
∵ y = 2 - 3cos(2x + 1)
∴ The phrase of shift:
∵ The horizontally shift is -C/B = - 1/2 = -1/2
∴ It moves 1/2 units to the left
∵ The vertically shift is D
∴ It moves 2 units up
