Gridlock: Functions


Price: $39.95

Format : DVD

Gridlock: Functions focuses on the definition of a function. Students develop a working definition of function that relates to its formal definition in a situation that requires the X-team to use examples and non-examples to discover characteristics of functions.

The episode begins with Holon seeking the X-team’s help to end the Others’ plot to do away with the rain forests. This situation introduces functions as an observable phenomenon.

The X-team explores functions when a remark causes R. J. to be placed in ‘gridlock’ while the rest of the X-team has to identify functions represented in graphs. Without knowing the formal definition of a function, the X-team has to use logical reasoning to determine the characteristics of a function.

This is done through looking for patterns in graphs and tables of functions and non-functions. The idea is that functions are those relations in which no two ordered pairs in the set have the same x-coordinate and different y-coordinates.

The program ends with a final look at the table that shows the growth of the rain forest deterioration. It is compared to the Rumor Problem with regard to the growth aspect.
