Provide an appropriate response.Why is it not possible to choose h and k, neither zero, so the parabola 
has its vertex at the origin?
What will be an ideal response?
The only way a parabola can have its vertex on the x-axis is if 
and the only way a parabola can have its vertex on the 
is if 
So the only way a parabola can have its vertex at the origin is if both h and k are zero.
