Function Machine

This virtual manipulative is designed to teach the concept of a function by allowing you to experiment with various functions.

- Observe the output of a function by dragging numbers from the top left corner to the IN chute of the function machine. The function machine will process the number and produce an output value.
- Make a guess what function the machine is using by observing the output. Use your guess to decide what the remaining entries of the table should be and type them into the boxes. If one of your entries doesn't match the computer function, you will get an error message.
