7-117.
  1. 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). If you do not have a graphing calculator at home, sketch the graph and check your answer when you get to class.

It is shifted π units to the left.

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