#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.
