Answer 2

Answer:

The standard equation of a parabola is

y=ax2+bx+c .

But the equation for a parabola can also be written in "vertex form":

y=a(x−h)2+k

In this equation, the vertex of the parabola is the point (h,k) .You can see how this relates to the standard equation by multiplying it out:

y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k .

This means that in the standard form, y=ax2+bx+c , the expression −b2a gives the x -coordinate of the vertex.
