Y-Intercept using the Dynamic Grapher Function
In Dynamic Graphing (CFX-9800G or CFX-9850G+)
Set graph window to initial setting Shift F3 INIT (F1)
setting the graph window -6.3 < X < 6.3 -3.1 < Y < 3.1
Select B-IN (F5) Select (F1) Y=AX+B Linear Eqaution EXE and will see Y1 = AX + B Dynamic Var :A
Set A = 2 B = 1 Select Range (F2) and see Y1 = AX + B Dynamic Range A Set
Start :-3 (EXE)
End : 4 (EXE)
Pitch : 2 (EXE)
EXE and see Y1 = AX + B Dynamic Var :A Set
A = 2
B = 1
Highlight B = 1
Select (F1) which makes B the dynamic variable DYNAmic (F6) AC/On to stop
Dynamic grapher EXIT key SHIFT SET UP (MENU) Arrow to Locus F1 to turn Locus on EXIT
Highlight B = (must reselect B as Dynamic Variable -- devault is A) SEL to select B as the dynamic variable DYNAmic (F6)
Student Questions
Have students describe what they see
Describe the impact of B changing
Describe similarities and differences in the graphs AC/On to stop Dynamic grapher
Speed can be altered EXE returns to the Dynamic grapher.
