Re: Hybrid functions on the ti-85.
I also prefer the division method.
However, you can use eval (or value on the TI-83). You may have to cursor
through the functions to find the one that gives you a value.
Try the following (on the 83).
y1=X/(X <= -2)
Y2=(-X)/((-2 < X)(X < 3))
y3=(X+3)/(X > 3)
NOTE: Undefined at X=3
Graph in Zoom 6.
Using the value option in the CALC menu, evaluate at several values
including -3, -2, -1.9999, 2.99999, 3, 3.00001
Notice that you will need to select the correct piece of the function
using the cursor up/down.
Also look in the table. This is illuminating.

Even better than multiplying each piece of a piecewise function
by a range expression (such as x>0) is to use a separate
y variable for each piece and *divide* by the range function. This
way you can still graph in connected mode, instead of dot. The
downside is that you can't use eval.
