A parabola - multiple representations for y = ax
Note:
Make sure that the V-Window is appropriate to see the graphs that you will be
drawing. Enter [SHIFT] [F3] then change the settings to the conditions shown here.
Go back to the Graph Function menu with [EXE] or [EXIT] .
Using, [A=1,2,3] at the end if the equation gives the effect of a 'dynamic graph'.
Example
Draw the graphs of y = 1x
