9-99.

**9-99.**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).

In the general equation *y* = sin(*x* − *h*) + *k*, which parameter moves the graph horizontally?
