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

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

b. 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).

Answer 1

The shift is \(2\pi\) units to the left.

( that is, 2pi units to the left )
