Trigonometry: Graphs: Horizontal and Vertical Shifts ...
Vertical Shifts To shift such a graph vertically, one needs only to change the function to f (x) = sin (x) + c, where c is some constant. Thus the $y$-coordinate of the graph, which was previously sin (x), is now sin (x) + 2. All values of y shift by two. The graph of y = f …
