7-117.

The graph at right was made by shifting the first cycle of $y = \sin x$ to the left.

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

It is shifted π units to the left.

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.

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