Basic activities in the GRAPH icon
This activity shows how the calculator can be used: to draw multiple lines; to see the relationship to the change in
the constant 'c' in y = mx + c and to draw multiple parabolas; to see the relationship to the change in the coefficient
'a' in y = ax + c.
2
A line - multiple representations for y = x + c
Note:
Make sure that the V-Window is appropriate to see the graphs that you will be drawing.
Enter [SHIFT] [F3] then the option that you require, in this case, [F1] for INITial. Go
back to the Graph Function menu with [EXIT] or [EXE].
Using, [A=-2,0,2] at the end if the equation gives the static effect of a 'dynamic graph'.
