In the applet below, note the three colored function graphs .
Another graph shown is the graph of the derivative of function .
The remaining graph is the graph of the 2nd derivative of function

*a*,*b*, and*c*.**Function***a*is shown as a blue graph.**Function***b*is shown as a brown graph.**Function**In each problem you generate here, One graph represents an original function*c*is shown as a purple graph.*f:**f:***Your goal is to determine which graph is which.**Simply check one of the checkboxes under each label on the top right side. After doing so, click "Check Answer". If your answers are not correct, work at correcting them.**Note:**You can zoom out if you would like to see all 3 graphs more from a distance. For a resource that dynamically illustrates the relationship between the graph of a function and the graph of its derivative function, see the GeoGebra applet BELOW THIS QUIZ APPLET.
