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?
