==Process (How to do the activity)==
open the Geogebra file
#open the Geogebra file
#start with values of a=o, b=0, c=0
##start with values of a=o, b=0, c=0
#change value of a to 1 (keeping b=0, c=0 and see what happens)
##change value of a to 1 (keeping b=0, c=0 and see what happens)
#change value of c to 1, 2, 3 etc (keeping a=1, b=0 and see what happens)
##change value of c to 1, 2, 3 etc (keeping a=1, b=0 and see what happens)
#change value of b to 1, 2, 3 etc (keeping a=1, c=0 and see what happens)
##change value of b to 1, 2, 3 etc (keeping a=1, c=0 and see what happens)
#In each of the above cases, discuss with students the meaning of the curve plotted and how the curve changes on change in values.

==Developmental Questions (What discussion questions)==
Distinction between linear equations and quadratic equations.
Distinction between linear equations and quadratic equations.
#When a=0, what happens?
#The quadratic equation graph is a distribution around x-axis. Can it be around y-axis? For it to be around y-axis how should the equation be?
#what does equal roots mean? with respect to distribution around x-axis?
#what does "c" represent?
