Question

Use your graphing calculator to graph the pair of functions for   together on a single coordinate system. (Make sure your calculator is set to radian mode.)  ​

Quizplus · Accepted Answer

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.
