1 - Click on the button  "click here to start" and MAXIMIZE the window obtained.

2 - Click start on the main menu.

3 - Answer the question by checking  a,b,c or d  in the lower part of the window.

You can review your answers and change them by selecting the desired letter. Once you have finished, press "finish" and you get a table with your answers and the right answers to compare with.

To start the test with another set of questions, press "reset".  

Record your number correct and incorrect and write the percentage achieved.  
(Goal is at least 80% accuracy.)

REQUIRED: 
Applet: Recognize functions 3
Drag and drop each graph in the box matching its equation.  Check your solutions and verify them for correctness.

REQUIRED:
Applet: Recognize graphs 3
Drag and drop each function in the box matching its graph.  Check your solutions and verify them for correctness.

Once you've tried each of the puzzles at least once, write a few sentences describing how you performed on matching the  appropriate functions and graphs.  Rate the level of difficulty of the puzzles, your speed and accuracy, and discuss which direction you prefer to match the pieces:  function-to-graph or graph-to-function.
