7-117.

The graph at right was made by shifting the first cycle of *y*= sin*x*to the left. Homework Help ✎How many units to the left was it shifted?

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(*x* − *h*) + *k*, which parameter moves the graph horizontally?
