You are able to trace the 'different parts' of a Piecewise Function using [SHIFT] [F1], then the

Finding regions that satisfy constraints as used in linear programming.

Algebraic substitution – numeric [in RUN-MAT]
This activity shows how the calculator can be used to substitute numerical values into algebraic expressions.
Algebraic substitution is where an independent numerical variable, usually x, is substituted into an equation for a
dependent variable, usually y.
To have '?' and ':' statements:
EXIT
Graph
KEY
KEY
Make sure that you have an appropriate View-Window to
see the graphs drawn.
By separating each graph by a colon ':' the calculator
generates them as a 'collective'. Tracing each to find
vertices etc is activated in the usual way, i.e. [SHIFT] [F1]
and then arrows to trace the graph and the
move from one graph to another.
replay arrows.
