Ok, it may be trivial to note that the 'linear function' was created
by limiting the domain of the independent variable (y) so that there
are only 2 possible values for (x)....... Namely: x' and x"
y' = a (x')^2 + b x' + c
y" = a (x")^2 + b x" + c
Since:
y'= 0
and:
y"= 0
y'= y"
Ok, let's now assume that in the above problem, the constants are:
a= .5
b= .7071067
c= -.25
vertex y= -.5
vertex x= -.7071067
Now, the question becomes "Can you write a 'general quadratic
function' that will incorporate all of the 'points' in the above
parabola and ALSO include a 2nd parabola which will intersect this
parabola, at it's vertex?"
If you can do this, you have solved the Twin Parabola Puzzle.
