3. Press (Yes) to delete the function or (No) to abort the procedure without deleting anything. • Using the above procedure to delete one line of a parametric function (such as Xt2) also will delete the applicable paired line (Yt2, in the case of Xt2).

Selecting Functions for Graphing
To specify the draw/non-draw status of a graph
1. On the Graph relation list, use
and
to highlight the relation you do not want to graph.
2. Press
