  1. 9-99. The graph at right was made by shifting the first cycle of y = sin(x) to the left. Homework Help ✎

    1. How many units to the left was it shifted?

    2. Figure out how to change the equation of y = sin(x) so that the graph of the new equation will look like the one in part (a).

In the general equation y = sin(xh) + k, which parameter moves the graph horizontally?
