4. Add the third piece of the function to Y1. This piece is
f(x)=6ìx for x≥5. It is entered as (6ìx) (x≥5). When x is
greater than or equal to 5, the test (x≥5) returns 1. The
third piece of the function is then equivalent to (6ìx)×1.
When X is less than 5, the test (x≥5) returns 0. The third
piece of the function is then equivalent to (6ìx)×0.
5. Enter these Window variable values.
Xmin=ë2 Ymin=ë2
Xmax=8 Ymax=10
Xscl=2 Yscl=1
6. Graph the piecewise function first in CONNECTED and
then DOT mode. Select CONNECTED on the MODE screen,
and then press ,. Then select DOT on the MODE
screen, and press ,.
