Final answer:
In the generic form, y = Asin(Bx + C) + D, the letter D tells us information about vertical shifts.
Step-by-step explanation:
In the generic form, y = Asin(Bx + C) + D, the letter D tells us information about vertical shifts.
The value of D represents the vertical shift of the graph, or how much it is moved up or down from its original position.
If D is positive, the graph will be shifted upward, and if D is negative, the graph will be shifted downward.
