3.16 Function Graphing
(continued)
On the TI-82 STATS, you can graph one or more new functions
without replotting existing functions. For example, store
editor and press s. Then store
to in the
Y Y=

and press s again. The function
the original function.
If you enter a list (Chapter 11) as an element in an expression,
the TI-82 STATS plots the function for each value in the list,
thereby graphing a family of curves. In
mode, it graphs all functions sequentially for the first element in
each list, and then for the second, and so on.
