You can use these TI-92 features to investigate models like the model
p(1) = 10
p(n) = 0.80 * p(n - 1)
which is one model for pollution in a lake. Remember to set the MODE to SEQUENCE for producing tables and graphs of sequences.
The screen below shows one way that the TI-92 can be used to investigate the slope of a tangent to a curve.
