1. With n indicating the segment number, does increase or decrease as n increases? Does increase or decrease as n increases? On your circuit diagram, draw arrows of different widths (or lengths) by each axon resistor to indicate the amount of current in that axon segment.

2.It should help to consider the behavior of () in the limiting cases. Examine the behavior of your model circuit. As x approaches 0, what happens to () as x becomes very large, what happens to ()? Compare with the behavior of each of the possible functional forms. Make your best guess for the functional form and sketch the corresponding graph of () vs. x. Explain your reasoning.
