3-16 Function Graphing
On the TI-83, you can graph one or more new functions
without replotting existing functions. For example, store

If you enter a list (Chapter 11) as an element in an
expression, the TI-83 plots the function for each value in
the list, thereby graphing a family of curves. In
graphing-order mode, it graphs all functions sequentially
for the first element in each list, and then for the second,
and so on.

Note: When using more than one list, the lists must have the same
dimensions.
