The pair of functions are:
$$f(x) = \sin(x)$$
$$g(x) = -\sin(2x)$$

To graph both functions on a single coordinate system:

1. Press the "y=" button on your calculator.
2. Enter "sin(x)" in the first equation (Y1).
3. Enter "-sin(2x)" in the second equation (Y2).
4. Press the "graph" button.

You will see that the graphs intersect at many points, but they do not overlap each other completely. The best choice is A because it shows the intersection points clearly.
